FUJITSU SEMICONDUCTOR DS501-00003-5v1-E DATA SHEET Memory FRAM 1 M Bit (128 K 8) MB85R1001A DESCRIPTIONS The MB85R1001A is an FRAM (Ferroelectric Random Access Memory) chip consisting of 131,072 words 8 bits of nonvolatile memory cells fabricated using ferroelectric process and silicon gate CMOS process technologies. The MB85R1001A is able to retain data without using a back-up battery, as is needed for SRAM. 10 The memory cells used in the MB85R1001A can be used for 10 read/write operations, which is a significant 2 improvement over the number of read and write operations supported by Flash memory and E PROM. The MB85R1001A uses a pseudo-SRAM interface. FEATURES Bit configuration : 131,072 words 8 bits 10 Read/write endurance : 10 times / byte Data retention : 10 years ( + 55 C), 55 years ( + 35 C) Operating power supply voltage : 3.0 V to 3.6 V Low power operation : Operating power supply current 10 mA (Typ) Standby current 10 A (Typ) Operation ambient temperature range : 40 C to + 85 C Package : 48-pin plastic TSOP (FPT-48P-M48) RoHS compliant Copyright 2011-2015 FUJITSU SEMICONDUCTOR LIMITED 2015.5MB85R1001A PIN ASSIGNMENTS (TOP VIEW) A11 1 48 OE A9 2 47 NC NC 3 46 VSS A8 4 45 A10 5 A13 44 CE1 6 WE 43 NC CE2 7 42 I/O8 A15 8 41 I/O7 NC 9 40 I/O6 VDD 10 39 I/O5 NC 11 38 I/O4 12 NC 37 VDD VSS 13 36 NC NC 14 35 I/O3 NC 15 34 I/O2 VDD 16 33 I/O1 NC 17 32 NC 18 A16 31 NC A14 19 30 NC A12 20 29 A0 A7 21 28 A1 A6 22 27 VSS A5 23 26 A2 24 A4 25 A3 (FPT-48P-M48) PIN DESCRIPTIONS Pin Number Pin Name Functional Description 1, 2, 4, 5, 8, 18 to 26, 28, 29, 45 A0 to A16 Address Input pins 33 to 35, 38 to 42 I/O1 to I/O8 Data Input/Output pins 44 CE1 Chip Enable 1 Input pin 7 CE2 Chip Enable 2 Input pin 6WE Write Enable Input pin 48 OE Output Enable Input pin Supply Voltage pins 10, 16, 37 VDD Connect all three pins to the power supply.
