CY14B101Q2A-SXI

CY14B101Q2A-SXI is a 1-Mbit (128K × 8) serial (SPI) nvSRAM. It combines a 1-Mbit nvSRAM with a non-volatile element in each memory cell with serial SPI interface. The memory is organized as 128K words of 8 bits each. The embedded non-volatile elements incorporate the QuantumTrap technology, creating the world’s most reliable non-volatile memory. The SRAM provides infinite read and write cycles, while the QuantumTrap cells provide highly reliable non-volatile storage of data. On power-up, data is restored to the SRAM from the non-volatile memory (RECALL operation). User can also initiate the STORE and RECALL operations through SPI instruction.

• 3.0V voltage, 1Mb density, with VCAP, 40MHz frequency
• 1-Mbit non-volatile static random access memory (nvSRAM) internally organized as 128K × 8
• RECALL to SRAM initiated on power-up (Power-Up RECALL) or by SPI instruction (Software RECALL)
• Infinite read, write, and RECALL cycles, 1million STORE cycles to QuantumTrap
• 40MHz, and 104MHz high-speed serial peripheral interface
• 104MHz clock rate SPI write and SPI read (with special fast read instructions)
• Supports SPI mode 0 (0, 0) and mode 3 (1, 1), software block protection for 1/4, 1/2, entire array
• Non-volatile STORE/RECALL, 8-byte serial number, manufacturer ID and product ID, sleep mode
• H/W protection using write protect (active low WP) pin, S/W protection using write disable
• 8-pin SOIC package, industrial temperature range from -40 to 85°C
