3-wire serial EEPROMs in SOT-23 package

19 November 2003 DSP, Micros & Memory

Microchip Technology has produced what it says is the industry's first 8 and 16 Kbit Microwire-compatible serial EEPROMs in a 6-lead SOT-23 package. The package footprint is approximately 72% smaller than the popular 8-lead narrow SOIC package and 56% smaller than an 8-lead TSSOP, while its height is 23% smaller than SOIC. Microchip's PMOS Electrically Erasable Cell process technology has allowed it to package the 93XX76A/B and 93XX86A/B serial EEPROMs in industry's only miniature packaging for 3-wire devices. It has also released its 93XX76C and 93XX86C devices in 8-lead MSOP, TSSOP, PDIP and SOIC packages. The devices also offer low write-cycle times, supply current and standby current. The 93XX76/86A devices support a x8-memory organisation while the 93XX76/86B devices support a x16 organisation. The 93LC76A/B/C and 93LC86A/B/C have operating voltages down to 2,5 V, active current of 1 mA and standby current of 1 µA. For even lower voltages, the 93AA76A/B/C and 93AA86A/B/C operate down to 1,8 V. The 93C76A/B/C and 93C86A/B/C are also available for 5 V applications.
