HT48R002 Holtek

The HT48R002 by Holtek is a SOP-8_150mil RoHS (Lead-free and RoHS compliant) integrated circuit designed for everyday applications. It is a fully encapsulated Memory IC with a -10uA low power operation and is designed to operate with a supply voltage ranging from 2.2V to 5V. The chip is capable of storing 16kbits of data and has 128-bytes RAM with EEPROM. The EEPROM provides data protection against parasites, wear and corruption. The chip also features a low power oscillator designed for cost effective timekeeping with a power consumption of 0.005µA (at 3V). It also includes a watchdog timer to reset the circuit if the system fails. The chip contains two 8-bit timer counters with internal clock and two 3-step pulse width modulators with digital frequency divider and a 16-bit value comparator. Additionally, it has 12 interrupt sources and one 7-bits prescaler. The device consumes less than 10µA in active mode and can achieve up to 10 years of data retention.
