ACE1202EM8X

Overview

The ACE1202EM8X is an 8-bit microcontroller from the Fairchild Semiconductor ACEX® 12xx product family, designed for low-power applications. It features a CPU core operating at a maximum clock frequency of 4 MHz and includes 2KB (2K x 8) of EEPROM program memory. The device provides 64 bytes of RAM and supports a supply voltage range of 1.8V to 5.5V. It is housed in an 8-pin SOIC package with 6 I/O lines.

Feature Summary

• Integrated 8-bit CPU core optimized for low power consumption
• Non-volatile 2KB EEPROM storage for program data retention
• Built-in peripherals including Low Voltage Detect (LVD), Power-On Reset (POR), Watchdog Timer (WDT), and Pulse Width Modulation (PWM)
• Internal oscillator system for simplified board design

Applications

• Low power embedded control systems
• Battery-operated devices requiring extended runtime
• Simple peripheral management interfaces
• Cost-sensitive consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices since this part may be discontinued. Ensure the specific suffix matches the required package and voltage specifications. Request original datasheets to validate electrical characteristics before integration.

Selection Notes

Select this component when an 8-bit architecture with integrated EEPROM is required for simple control tasks. Consider the 1.8V to 5.5V supply range for flexible power designs. Evaluate the 4 MHz speed limit against application timing requirements. Compare pin count and peripheral availability with other members of the ACEX family for optimal fit.

Part Context

This microcontroller belongs to the ACEX® 12xx series, which targets low-cost, low-power embedded applications. The family shares common architectural features but varies in memory size and package options. The EM8X suffix denotes the specific 8-pin SOIC variant within this lineup.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Verify compatibility regarding pinout, voltage levels, and instruction set architecture before substitution.
