ACE1502

Highly integrated, ultra-low voltage microcontroller that lowers part count and extends battery life in portable/handheld applications

The ACE1502 family of microcontrollers is a dedicated programmable monolithic integrated circuit for applications requiring high performance, low power, and small footprint. This product family has an 8-bit microcontroller core, 64 bytes of RAM, 64 bytes of data EEPROM and 2K bytes of code EEPROM. Its on-chip peripherals include a multifunction 16-bit timer, a watchdog/idle timer, and programmable under-voltage detection circuitry. On-chip clock and reset functions reduce the number of required external components. Product is available in 8 and 14 pin SOIC, TSSOP, and DIP package.

Features

- 2K bytes on-chip code EEPROM
- 64 bytes data EEPROM
- Watchdog/idle timer
- Multi-input wake-up on all eight general purpose I/O pins
- 16-bit multifunction timer with difference capture
- High current I/O pins (± 7mA on all I/O pins)
- In-circuit programmable without requiring high voltages (typically 12V)

Benefits

- Extends battery life (<100nA standby/halt)
- Minimizes board space though integrated peripherals (on-chip clock, timers, EEPROM and high current I/O)
- Low mounted height (TSSOP-8 package)

Applications

- RKE (Remote Keyless Entry)
- Handheld Remotes
- Appliances, Lamp Dimmers
- Battery Management, Battery ID
