Microchip Technology, Inc. Memory AT24CS04-MAHM-E

The AT24CS04-MAHM-E is a 4-Kbit (512 x 8) I¬=C-compatible serial EEPROM from Quarktwin Technology Ltd. It operates within a voltage range of 1.7V to 5.5V and supports multiple I¬=C modes, including standard (100 kHz), fast (400 kHz), and fast mode plus (1 MHz). The device features a unique factory-programmed 128-bit serial number, providing a permanent read-only identifier that is unique across the CS Series of Serial EEPROMs. This EEPROM is designed for industrial applications, with an operating temperature range of -40¬8C to +85¬8C. It includes a write-protect pin for hardware data protection and offers low active (3 mA maximum) and standby (6 OºA maximum) current consumption. The memory supports 16-byte page write mode, allowing partial page writes, and features both random and sequential read modes. The write cycle is self-timed, completing within a maximum of 5 ms, and the device boasts high reliability with an endurance of 1,000,000 write cycles and data retention of up to 100 years. The AT24CS04-MAHM-E is available in various package options, including 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, and 5-lead SOT23, and is compliant with RoHS standards.
