PGA460-Q1: Regarding external EEPROM requirement

padmaraj Chipre

Part Number: PGA460-Q1
Other Parts Discussed in Thread: PGA460, BOOSTXL-PGA460

Hi,

We are using PGA460-Q1 in our design. We have few queries.

In the EVM, there is a SPI SRAM, used to store the output of PGA460. Is that compulsory to have SRAM in our design?

Can we communicate to MCU directly through internal EEPROM of PGA460 without  external SRAM ?

Kindly requesting you to support as we want this asap.

Thank you in advance.

    padmaraj,

    The PGA460 does not require any external EEPROM memory, and can be operated using only UART. The BOOSTXL-PGA460 EVM only includes the external EEPROM for the specialized test use-case of capturing the synchronous mode output data, which is not a standard feature. The PGA460's internal EEPROM and RAM are able to store all the necessary configuration and result information, which the external microcontroller can read directly via UART (TXD and RXD only, SCLK can be pulled to ground via a 10kOhm resistor if not used).
