ANV31A81W
256Kb Serial SPI nvSRAM
The Anvo-Systems Dresden ANV31A81W is a 256Kb
serial SRAM with a non-volatile SONOS storage ele-
ment included with each memory cell, organized as
32k words of 8 bits each. The devices are accessed by
a high speed SPI-compatible bus. The ANV31A81W is
enabled through the Chip Enable pin (E) and accessed
via a 3-wire interface consisting of Serial Data Input
(SI), Serial Data Output (SO) and Serial Clock (SCK).
All programming cycles are self-timed, and no separate
ERASE cycle is required before STORE.
The serial SRAM provides the fast access & cycle
times, ease of use and unlimited read & write endur-
ance of a normal SRAM. Dedicated safety features
supporting high data accuracy.
With Secure WRITE operation the ANV31A81W
accepts address and data only when the correct 2 Byte
CRC, generated from the 15 bit address and 64 Byte
data, is transmitted. Corrupt data cannot overwrite
existing memory content and even valid data would not
overwrite on a corrupted address. With status register
bit 4 the success of the Secure WRITE operation can
be monitored. In case of corrupt data bit 4 will be set
volatile to high. With Secure READ operation the
ANV31A81W calculates the correct 2 Byte CRC paral-
lel to data transfer. The 2 Byte CRC is transmitted after
64 Bytes of data have been transmitted.
Both STORE and RECALL operations are available
under instruction control.
On power up, data is automatically restored to the
SRAM (the Power Up Recall operation).
BLOCK WRITE Protection is enabled by programming
the status register with one of four options to protect
blocks.
A 2 Byte non-volatile register supports the option of a 2
Byte user defined serial number. This register is under
customer control only.
Status register bit 5 will control page and block roll over
modes.
