Debug Interface

The ADSPSC835W-EV-SOM provides a JTAG connection via P6. This is for attaching an emulator, such as the ICE-1000 or ICE-2000 for debugging.

When the ADSPSC835W-EV-SOM is connected to a carrier board the Debug Agent on the carrier board can be used. To use this Debug Agent, all postions on SW1 (on the carrier board) must be in the ON position. If an emulator, such as the ICE-1000 or ICE-2000, is used instead all postions on SW1 must be in the OFF position.

A second JTAG connector P2 is used with a JLNIK emulator to connect to the R5 Safety Core on the ADSPSC835W-EV-SOM board.

Board Power

The ADSPSC835W-EV-SOM is powered via USB Type C when the board is in standalone mode. When in this mode the jumper on JP1 should be on Pins 1-2 to select power input from USB Type C. When the ADSPSC835W-EV-SOM is connected to a carrier board the power is supplied via the carrier board. When in this mode the jumper on JP1 should be on Pins 2-3 to select power input from the carrier board.

Power-On-Self Test

The Power-On-Self-Test Program (POST) tests all the EZ-KIT carrier board peripherals and validates functionality as well as connectivity to the processor. Once assembled, each EZ-KIT carrier board is fully tested for an extended period of time with POST for all the compatible SoM modules. All EZ- KIT carrier boards are shipped with POST preloaded into flash memory. The POST is executed by resetting the board and connecting the USB To UART to your PC with an open terminal window. The POST also can be used as a reference for a custom software design or hardware troubleshooting.

Note that the source code for the POST program is included in the Board Support Package (BSP) along with the readme file that describes how the board is configured to run POST.

Example Programs

Example programs are provided with the ADSPSC835W-EV-SOM Board Support Package (BSP) to demonstrate various capabilities of the product. The programs can be found in the ADSPSC835W-EV-SOM\examples installation folder. Refer to the readme file provided with each example for more information.

IS25LP512M – 512M-bit Serial Flash Memory with Dual and Quad SPI

The IS25LP512M Serial Flash memory offers a versatile storage solution with high flexibility and performance in a simplified pin count package. ISSI’s “Industry Standard Serial Interface” Flash is for systems that require limited space, a low pin count, and low power consumption. The device is accessed through a 4-wire SPI Interface consisting of a Serial Data Input (SI), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins, which can also be configured to serve as multi-I/O (see pin descriptions).

The device supports Dual and Quad I/O, as well as standard, Dual Output, and Quad Output SPI. Clock frequencies of up to 133MHz allow for equivalent clock rates of up to 532MHz (133MHz x 4) which equates to 66.5Mbytes of data throughput. The IS25xE series of Flash adds support for DTR (Double Transfer Rate) commands that transfer addresses and read data on both edges of the clock. These transfer rates can outperform 16-bit Parallel Flash memories, allowing for efficient memory access to support XIP (eXecute In Place) operation.

The memory array is organized into programmable pages of 256/512 bytes. This family supports page program mode where 1 to 256/512 bytes of data are programmed in a single command.

QPI (Quad Peripheral Interface) supports 2-cycle instructions, further reducing instruction times. Pages can be erased in groups of 4Kbyte sectors, 32Kbyte blocks, 64K/256Kbyte blocks, and/or the entire chip. The uniform sector and block architecture allows for a high degree of flexibility so that the device can be utilized for a broad variety of applications requiring solid data retention.

LT8636 – 42V, 5A/7A Peak Synchronous Step-Down Silent Switcher with

2.5µA Quiescent Current

The LT8636 synchronous step-down regulator features Silent Switcher architecture designed to minimize EMI emissions while delivering high efficiency at high switching frequencies. Peak current mode control with a 30ns minimum on-time allows high step-down ratios even at high switching frequencies.

The LT8636’s ultralow 2.5µA quiescent current—with the output in full regulation—enables applications requiring highest efficiency at very small load currents. A CLKOUT pin enables synchronizing other regulators to the LT8636.

Burst Mode operation enables ultralow standby current consumption, forced continuous mode can control frequency harmonics across the entire output load range, or spread spectrum operation can further reduce EMI emissions. Soft- start and tracking functionality is accessed via the TR/SS pin, and an accurate input voltage UVLO threshold can be set using the EN/UV pin.

LTC3307A – 5V, 3A Synchronous Step-Down Silent Switcher in 2mm × 2mm

LQFN

The LTC3307A is a very small, high efficiency, low noise, monolithic synchronous 3A step-down DC/DC converter operating from a 2.25V to 5.5V input supply. Using constant frequency, peak current mode control at switching frequencies up to 3MHz and minimum on-time as low as 22ns, this regulator achieves fast transient response with small external components. Silent Switcher architecture minimizes EMI emissions.

The LTC3307A operates in forced continuous or pulse skip mode for low noise, or low-ripple Burst Mode operation for high efficiency at light loads, ideal for battery-powered systems. The IC regulates output voltages as low as 500mV. Other features include output overvoltage protection, short-circuit protection, thermal shutdown, clock synchronization, and up to 100% duty cycle operation for low dropout. The device is available in a low profile 12- lead 2mm × 2mm × 0.74mm LQFN package with exposed pad for low thermal resistance.

LTC3310S – 5V, 10A Synchronous Step-Down Silent Switcher 2 in 3mm × 3mm

LQFN

The LTC3310S is a very small, low noise, monolithic step-down DC/DC converter capable of providing up to 10A of output current from a 2.25V to 5.5V input supply. The device employs Silent Switcher 2 architecture with internal hot loop bypass capacitors to achieve both low EMI and high efficiency at switching frequencies as high as 5MHz. For systems with higher power requirements, multi-phasing parallel converters is readily implemented.

The LTC3310S uses a constant-frequency, peak current mode control architecture for fast transient response. A 500mV reference allows for low voltage outputs. 100% duty cycle operation delivers low drop out.

Other features include a power good signal when the output is in regulation, precision enable threshold, output overvoltage protection, thermal shutdown, a temperature monitor, clock synchronization, mode selection and output short circuit protection.

ADP151 – Ultralow Noise, 200 mA, CMOS Linear Regulator

The ADP151 is an ultralow noise, low dropout (LDO) linear regulator that operates from 2.2 V to 5.5 V and provides up to 200 mA of output current. The low 135 mV dropout voltage at 200 mA load improves efficiency and allows operation over a wide input voltage range.

Using an innovative circuit topology, the ADP151 achieves ultralow noise performance without the necessity of a bypass capacitor, making the device ideal for noise-sensitive analog and RF applications. The ADP151 also achieves ultralow noise performance without compromising the power supply rejection ratio (PSRR) or transient line and load performance. The low 265 μA of operating supply current at 200 mA load makes the ADP151 suitable for battery- operated portable equipment.

The ADP151 also includes an internal pull-down resistor on the EN input.

The ADP151 is specifically designed for stable operation with tiny 1 μF, ±30% ceramic input and output capacitors to meet the requirements of high performance, space constrained applications.

The ADP151 is capable of 16 fixed output voltage options, ranging from 1.1 V to 3.3 V.

Short-circuit and thermal overload protection circuits prevent damage in adverse conditions. The ADP151 is available in tiny 5-lead TSOT, 6-lead LFCSP, and 4-ball, 0.4 mm pitch, halide-free WLCSP packages for the smallest footprint solution to meet a variety of portable power application requirements.
