The BA45F0082 has a 2K×15 Flash Program Memory, a 128-byte Data Memory, a 64-byte True Data EEPROM and 6-level subroutine nesting. The device also has a range of practical peripheral functions such as 10-bit and16-bit timer modules, a multi-channel 12-bit A/D converter, a low power consumption high speed internal RC oscillator and so on. The fully integrated highly accurate internal high speed RC oscillator can provide a fixed system frequency of 2MHz with a current consumption of only 200µA at a power supply voltage of 3V. The device is especially suitable for use in independent temperature detecting alarms.

The BA45FH0082 contains all the functions of the BA45F0082 but also includes a two line type bus communication circuit and a 3.3V LDO, thus reducing greatly the required number of external components. The device is suitable for bus connected fire protection system peripheral product applications, such as acousto-optical alarms, temperature detectors, Input/Output modules, fire door monitoring in addition to many others.

The BA45F0082 is supplied in a 16-pin NSOP package type while the BA45FH0082 is supplied in 16-pin NSOP and 20-pin SSOP package types. These package types make them applicable for use in different fire protection peripheral product applications.
