Dear customer st LAPIS Semiconductor Co., Ltd. LAPIS Semiconducto), on the 1 day of October, 2020, implemented the incorporation-type company split (shinsetsu-bunkatsu) in which LAPIS established a new company, LAPIS Technology Co., Ltd. (LAPIS Technology) and LAPIS Technology succeeded LAPIS Semiconductors LSI business. Therefore, all references toLAPIS Semiconductor Co., Ltd,LAPIS Semiconducto and/orLAPI in this document shall be replaced withLAPIS Technology Co., Ltd Furthermore, there are no changes to the documents relating to our products other than the company name, the company trademark, logo, etc. Thank you for your understanding. LAPIS Technology Co., Ltd. October 1, 2020 FEDR44V100A-01 Issue Date: Sep. 04, 2017 MR44V100A 1M Bit(131,072-Word -Word 8-Bit) FeRAM (Ferroelectric Random Access Memory) I2C GENERAL DESCRIPTION The MR44V100A is a nonvolatile 131,072-word x 8-bit ferroelectric random access memory (FeRAM) developed in the ferroelectric process and silicon-gate CMOS technology. The MR44V100A is accessed using Two-wire Serial Interface ( I2C BUS ).Unlike SRAMs, this device, whose cells are nonvolatile, eliminates battery backup required to hold data. This device has no mechanisms of erasing and programming memory cells and blocks, such as those used for various EEPROMs. Therefore, the write cycle time can be equal to the read cycle time and the power consumption during a write can be reduced significantly. The MR44V100A can be used in various applications, because the device is guaranteed for the write/read 12 tolerance of 10 cycles per bit and the rewrite count can be extended significantly. FEATURES 131,072-word 8-bit configuration I2C BUS Interface A single 3.3 V typ. (1.8V to 3.6V) power supply Operating frequency: 3.4MHz(Max) HS-mode 1MHz(Max) F/S-mode Plus 12 Read/write tolerance 10 cycles/bit Data retention 10 years Guaranteed operating temperature range 40 to 85C Low power consumption Power supply current ( 3.4MHz) 1.1mA(Max.) Standby mode supply current 10A(Typ.), 50A(Max.) Sleep mode supply current 0.1A(Typ.), 2A(Max.) Package options: 8-pin plastic SOP (P-SOP8-200-1.27-T2K) RoHS (Restriction of hazardous substances) compliant 1/18
