SMS24 数据手册 ( 数据表 ) - Summit Microelectronics

INTRODUCTION
The SMS24 is a configurable and in-system programmable second generation 8 pin supervisory circuit. This single device is adaptable to provide the optimum functionality for a given system or sub-system. User programmable functions available — reset pulse width, watchdog delays, and voltage monitor thresholds — eliminate external components and allow standardization to enhance system reliability. Additionally, 4K bits of general purpose EEPROM is available on all configurations. The SMS24 is available in six pin configurations, and is compatible with all Summit programmable devices and other I2C components.
