Holtek Releases Two New High Capacity Serial EEPROMs

March 27, 2006

Holtek Semiconductor's EEPROM devices are supplied in two interface types, the I²C and 3-Wire types, and to add to this product range, Holtek is delighted to announce the addition of two new EEPROM devices. Known as the HT24LC32 and HT93LC86, these two new devices now expands the Holtek's EEPROM range to span a capacity from 1K to 64K, enabling them to meet the demands of a wide array of customers.

The HT24LC32 has a 2-wire serial interface and has a capacity of 32K bits. The device has a working voltage range from 2.4V to 5.5V, a memory structure of 4096 x 8 bits, a maximum operating frequency of 400kHz and an operating and standby current of 5mA and 5uA respectively. The HT24LC32 supports both single byte write and 32-byte page write operations as well as random read and sequential read operations. A write protect pin is provided which is used to protect the complete contents of the EEPROM. The device has a 1 million rewrite cycle capability and a data retention lifespan of 40 years.

The HT93LC86 utilises a 3-wire serial interface and has a capacity of 16K bits. The device has a wide operating voltage range of 2.2V to 5.5V, and can be configured into a memory structure of either 1024 x 16 or 2048 x 8. Instructions can be used to protect the contents of the EEPROM. The device has an operating and standby current of 5mA and 10uA respectively and can withstand up to 1 million write cycles. After experiencing 100,000 rewrite cycles the device will still have a data retention lifespan of up to 10 years.

These two devices are supplied in 8-pin, SOP, DIP and TSSOP package types, making them suitable for applications requiring high capacity and small packages, such as HDTV, digital televisions, set-top boxes, cordless mice, cordless internet cards, ADSL, network circuits and other consumer product applications.
