SM28VLT32 is a 32-Megabit Flash Memory designed to store program code and/or data from acquisition. The wide temperature rating of this device makes it ideal for applications that need to perform reliably in harsh environments. SM28VLT32 with its serial peripheral interface (SPI) offers low pin count for additional reliability and easy assembly in these applications.

The memory is partitioned as sectors to provide addressing of 2-M words of 16 bits each. Thus, the memory address is 21 bits wide.

SM28VLT32 supports serial peripheral interface to read/write/erase data in the flash memory. The interface is compliant with mode 0 (CPOL = 0, CPHA = 0) and 3 (CPOL = 1, CPHA = 1). Asserting CS# enables the device to enter communication mode. With CS# de-asserted, the device ignores all activity on the SPI pins. As shown in , multiple SM28VLT32 devices can be controlled from a single Master by independently controlling CS# pins in order to realize larger memory in the application. Asserting the HOLD# pin (while CS# is also asserted) will let the device ignore activity on the other SPI input pins (SCK and SI).

The SM28LVT32 supports a hardware data protection scheme using the WP# pin. Erase and program operations are inhibited if WP# is low.

HTFLASHEVM — HTFLASHEVM Evaluation Module

The HTFLASHEVM is designed for verification of the SM28VLT32 in extreme environments. The EVM, as shipped, is ready for test up to 200°C with the following exceptions. The decoupling capacitors need to be swapped from standard temperature range to 200°C rated through-hole components. This (...)
