New 4 Mbit EEPROM memory device provides designers with flexibility
and proven reliability
Portable consumer and medical devices including fitness trackers, hearing aids and glucose monitors as well as industrial, automotive and other systems often use customer-specific data sets to optimize the consumer experience. These non-volatile data sets – including calibration constants, background conditions, user preferences and changing noise environments – often are adjusted by the end system or user a few bytes at a time. Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) is the memory of choice for these applications providing nonvolatility, byte-level control, ease-of-use and low-power consumption. Microchip Technology Inc. (Nasdaq: MCHP) today announced its new, highest-density EEPROM – the 25CSM04.
At 4 Mbit,
Microchip’s new EEPROM becomes the largest EEPROM available to developers,
doubling the 2 Mbit density designers previously were limited to. Until now
developers have used lower-cost NOR Flash integrated circuits (ICs) for any 2
Mbit+ nonvolatile data set application. Because EEPROM offers performance
advantages over NOR Flash, Microchip has responded to customer requests by
introducing a larger 4 Mbit EEPROM. EEPROM
advantages include a lower standby current (2 µA vs. 15 µA); the ability to
perform single-byte, multi-byte, and full-page writes; shorter sector
erase/rewrite times (5ms vs.300ms); and more erase/rewrite cycles (1M vs
100K).
“Pushing the top end of
what is possible with serial EEPROM supports product innovation,” said Randy
Drwinga, vice president of Microchip’s memory products division. “Designers can
now reevaluate their systems and leverage this new technology to optimize
design performance.”
The 25CSM04 becomes part of
Microchip’s extensive nonvolatile memory product portfolio that integrates
within Microchip’s total system solutions built around its 8-bit, 16-bit,
and 32-bit micro-controllers and micro-processors. Microchip’s
extensive memory product family includes serial EEPROMs, NOR Flash, SRAM,
and EERAM in all standard serial buses and all standard densities from 128-bit
to 64 Mbit.
As a technology
innovator in serial EEPROM for more than 30 years, Microchip delivers
approximately one billion EEPROM devices annually.
Development Tools
Microchip’s 4 Mbit serial EEPROM devices are supported by
the MPLABÃ’ Starter Kit for Serial Memory Products. The kit
includes a serial memory interface board, serial EEPROM starter pack, USB
cable, CD containing the MPLAB X Integrated Development Environment (IDE), Total Endurance™ software
model and a serial EEPROM interface tool.
