Microchip Technology, Inc. Memory 93AA66-I/P

The Microchip 93AA66 is a 4Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for low voltage applications, operating within a temperature range of -40¬8C to +85¬8C. It features a memory organization that can be configured as 512 x 8 bits or 256 x 16 bits, depending on the ORG pin setup. The device operates with a single supply voltage as low as 1.8V, making it suitable for low-power applications. This EEPROM utilizes a 3-wire serial Microwire interface and supports a clock frequency of up to 2 MHz. It has a typical active read current of 70 ¬µA and a standby current of 2 ¬µA at 1.8V. The device is rated for 1,000,000 erase/write cycles and offers data retention exceeding 200 years. It is available in an 8-pin PDIP or SOIC package, ensuring compatibility with various designs. Engineers should consider this EEPROM for applications requiring reliable non-volatile memory with low power consumption and a wide operating temperature range.
