Microchip Rolls Out 1- to 16- kbit Microwire Compatible Devices

10/28/2003 - Microchip Technology Inc, a leading provider of microcontroller and analog semiconductors, announced the industry’s first 8-kbit and 16-kbit Microwire® compatible serial EEPROMs in a 6-lead SOT-23 package. Approximately the size of the equal symbol (=) on the key of a standard keyboard, this device is well suited for portable and handheld applications where board space is at a premium.

Utilizing Microchip’s patented, advanced PMOS Electrically Erasable Cell (PEEC) process technology, the 93XX76A/B and 93XX86A/B devices enable designers to put higher-density parts in applications requiring smaller footprints or lower profiles. Microchip is also introducing its 93XX76C and 93XX86C devices, which are available in 8-lead MSOP, TSSOP, PDIP and SOIC packages.

“Microchip continues to lead the industry with its package choices, write times, supply current and speed in serial EEPROM,” said Barry Blixt, product marketing manager for the Memory Product Division at Microchip. “Microchip’s patented PEEC technology enables the company to offer unique solutions and the industry’s only miniature packaging for 3-wire devices. Now the entire 3-wire family is available in 6-lead SOT-23 packages from 1-kbit to16-kbits.”

These new devices offer lower write-cycle times, lower supply current and lower stand-by current. The 93XX76A and 93XX86A devices are designed to support a x8-memory organization and the 93XX76B and 93XX86B devices support a x16-memory organization. The 93XX76C and 93XX86C devices feature a standard Word Organization (ORG) pin, allowing for selection of either the 8- or 16-bit word lengths.

The 93LC76A/B/C and 93LC86A/B/C have operating voltages down to 2.5 volts, active current of 1 milliamp (mA) and standby current of 1 microamp (µA). For battery-powered applications with even lower voltage requirements, the 93AA76A/B/C and 93AA86A/B/C enable operation down to 1.8 volts. A third series, the 93C76A/B/C and 93C86A/B/C, are also available for standard 5-volt applications requiring a higher power-on-reset (POR) voltage threshold.

The footprint of the 6-lead SOT-23 package is only of 8.26 mm2, which is approximately 72 percent smaller than the popular 8-lead narrow SOIC package and 56 percent smaller than an 8-lead TSSOP package. The device profile has a height of approximately 1.2-mm, which is 23 percent lower than a SOIC package. This smaller package offers designers an unprecedented level of flexibility in space-constrained applications.

Low cost is the driving force for serial EEPROMs in remote controls, home alarms, PC-card and peripheral markets, and size and weight are additional considerations in the portable and hand-held arena. Microchip designed its latest Microwire compatible series into the smallest packages available to meet both key market drivers. Applications targeted for these devices include automotive, consumer appliances, remote controls, medical devices, portable/personal electronics, power supplies, PC peripherals, hand-held and wearable PCs, telecommunications (including phones and pagers), security alarms and sensors.

Pricing in 10,000-unit quantities is $0.40 each for the 93XX76A, 93XX76B and 93XX76C devices, and $0.44 each for the 93XX86A, 93XX86B and 93XX86C devices.
