Description
FUJITSU SEMICONDUCTOR DATA SHEET DS501-00007-0v01-E Memory FRAM 256 K (32 K × 8) Bit SPI MB85RS256A ■ DESCRIPTION MB85RS256A is a FRAM (Ferroelectric Random Access Memory) chip in a configuration of 32,768 words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells. MB85RS256A adopts the Serial Peripheral Interface (SPI). The MB85RS256A is able to retain data without using a back-up battery, as is needed for SRAM. The memory cells used in the MB85RS256A can be used for 1010 read/write operations, which is a significant improvement over the number of read and write operations supported by Flash memory and E2PROM. MB85RS256A does not take long time to write data unlike Flash memories nor E2PROM, and MB85RS256A takes no wait time. ■ FEATURES Bit configuration Operating power supply voltage Operating frequency Serial Peripheral Interface Operating temperature range Data retention High endurance Package : : : : : : : : 32,768 words × 8 bits 3.0 V to 3.6 V 25 MHz (Max) SPI (Serial Peripheral Interface) Correspondent to SPI mode 0 (0, 0) and mode 3 (1, 1) −40 °C to +85 °C 10 years (+55 °C) 10 Billion Read/writes 8-pin plastic SOP (FPT-8P-M02) Copyright©2011 FUJITSU SEMICONDUCTOR LIMITED All rights reserved 2011.6 www.DataSheet4U.net MB85RS256A ■ PIN ASSIGNMENT (TOP VIEW) CS 1 8 VCC SO 2 7 HOLD WP 3 6 SCK GND 4 5 SI (FPT-8P-M02) ■ PIN FUNCTIONAL DESCRIPTIONS Pin No. Pin Na...
