Overview
The ACE1502EN14 is an 8-bit microcontroller from the ACEx family, fabricated using fully static CMOS technology. It features a 2K byte code EEPROM, 64 bytes of data EEPROM, and 64 bytes of RAM. The device operates on a single supply voltage ranging from 1.8V to 3.6V and supports an internal oscillator with a 1µs instruction cycle time. It includes a 16-bit multifunction timer, watchdog timer, and programmable under-voltage detection. The component is housed in a 14-pin DIP package and supports in-circuit programming.
Feature Summary
- Integrated Arithmetic Controller Engine optimized for block encryption and bit manipulation
- On-chip Hardware Bit-Coder designed for IR/RF data transmission encoding
- Multi-input wake-up capability across all general-purpose I/O pins
- Low power HALT mode with minimal current consumption
Applications
- Remote Keyless Entry systems
- IR/RF data transmission interfaces
- Block encryption applications
- Low power embedded control systems
Procurement Notes
Verify the specific suffix EN14 corresponds to the 14-pin DIP package variant. Confirm the operating temperature range matches the E or V grade requirements for your design environment. Check current availability status as this component may be subject to end-of-life restrictions.
Selection Notes
Select this component for designs requiring low power consumption and small form factors. Ensure the application utilizes the 1.8V to 3.6V supply range. Consider the 14-pin package constraints if more GPIOs are needed compared to the 8-pin version.
Part Context
The ACE1502 belongs to the ACEx product family, which provides arithmetic controller engines for low-power applications. This family is characterized by its modified Harvard architecture and specialized instruction set for efficient data manipulation and encryption tasks.
Replacement Considerations
Consult official documentation for direct substitutes within the ACE1502 family, such as the ACE1502VN for 8-pin configurations. Verify pin compatibility and electrical specifications before integrating alternative part numbers.
FAQ
What is the maximum external clock frequency supported?
The ACE1502 supports an external clock frequency up to 8 MHz.
How many interrupt sources does the core support?
The ACEx microcontroller core supports four interrupt sources: Timer0, Timer1, Multi-Input Wakeup, and Software Interrupt.
