ACE1501EMT8X

Overview

The ACE1501EMT8X is an 8-bit microcontroller from the ACEx family, manufactured by Fairchild Semiconductor. It utilizes the ACE1502 core and features 1 kB of EEPROM program memory and 64 B of data RAM. The device operates within a voltage range of 1.8 V to 3.6 V and supports a maximum clock frequency of 25 MHz. It includes 8 I/O lines and twelve timers/counters. Packaged in TSSOP-8 for surface mount installation, it functions without an ADC and supports a 4-Wire interface.

Feature Summary

• Supports in-circuit programming of code EEPROM, data EEPROM, and initialization registers.
• Designed for high performance with low power consumption requirements.
• Optimized for applications requiring small physical size.

Applications

• Low power embedded systems
• High performance control applications
• Small size constrained designs

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package integrity and pin alignment against TSSOP-8 specifications. Check for obsolescence status as the part may be discontinued. Ensure environmental compliance documentation matches project requirements. Validate electrical parameters against datasheet limits before integration.

Selection Notes

Select this component when an 8-bit MCU with arithmetic controller capabilities is required. Consider the 25 MHz speed and 1.8 V minimum operating voltage for battery-powered devices. Evaluate the 64 B RAM limit for complex algorithm storage needs. Compare against other ACEx variants if different memory sizes or I/O counts are necessary.

Part Context

This part belongs to the ACEx (Arithmetic Controller Engine) family, which includes models like ACE1001, ACE8001, ACE1101, ACE1202, and ACE1502. These MCUs are engineered for efficiency and compactness. The ACE1501 variant specifically offers higher clock speeds compared to some lower-end family members while maintaining the same architectural benefits.

Replacement Considerations

Public confirmed substitute part numbers were not identified in available documentation. Verify compatibility with existing PCB layouts if considering alternative ACEx family members such as ACE1502-based variants.
