Microchip Technology, Inc. Dsc, 100Mhz, 64Kb, Uqfn-48 Rohs Compliant Microchip DSPIC33CK64MC105-I/M4

The Microchip 47L64 is a 64-Kbit serial EERAM device that combines an SRAM memory core with hidden EEPROM backup, allowing for unlimited reads and writes. It features a symmetrical read/write operation and utilizes an I¬=C interface with standard speeds of 1 MHz, 400 kHz, and 100 kHz. The SRAM is organized as 8,192 x 8 bits, and the device operates within a voltage range of 2.7V to 3.6V, making it suitable for various applications. This device includes low-power CMOS technology, with a maximum active current of 1 mA and a standby current of 200 ¬µA. It is designed to automatically back up SRAM data to EEPROM during power disruptions, ensuring data integrity with a minimum of 100,000 backups and a retention period of up to 100 years at 55¬8C. The operating temperature range is from -40¬8C to +85¬8C, and it offers ESD protection exceeding 2,000V. The 47L64 is available in multiple package types, including 8-Lead SOIC and 8-Lead TDFN, and requires an external capacitor for proper operation during backup processes. This product is ideal for applications requiring reliable data retention and low power consumption.
