Serial EEPROMs with single I/O bus interface

DSP, Micros & Memory

25 June 2008 DSP, Micros & Memory

Microchip has released a new family of serial EEPROM devices with a single I/O bus interface. The devices are based on Microchip's patent-pending UNI/O memory-device protocol.

The 11XX010, 11XX020, 11XX040, 11XX080 and 11XX160 are claimed to be the first single I/O EEPROM devices that can support data rates from 10 kHz to 100 kHz; and the only 1, 2, 4, 8 and 16 Kbit EEPROMs available in a 3-pin SOT-23. The new devices also include features such as status registers, software write protection for ¼, ½ or full array; noise filtering, and robust ESD protection for high reliability.

The UNI/O bus and EEPROM devices were developed in response to market trends toward smaller consumer-electronic products with more features and functionality. With this new bus, only one I/O pin is needed for communication between the EEPROM device and a host microcontroller (MCU).

Evaluation is simplified because the UNI/O memory devices are available in 8-pin packages with pin-outs that overlay any standard I²C or SPI EEPROM socket. This means that existing hardware can be used with the available UNI/O software drivers for a rapid test.

The UNI/O memory devices are supported by the new MPLAB Starter Kit for Serial Memory Products, the MPLAB PM3 Universal Device Programmer and by software drivers available for Microchip's PIC MCUs.

The new devices are offered in two versions - the 11LCXX0 versions operate from 2,5 V to 5,5 V, and the 11AAXX0 versions operate from 1,8 V to 5,5 V. All of the new ICs are available in 3-pin SOT-23 as well as 8-pin PDIP, MSOP, SOIC and 2 x 3 mm TDFN packages.
