COP8SAC7SLB8

Overview

The COP8SAC7SLB8 is an 8-bit CMOS microcontroller from the COP8SA family, featuring 4KB OTP EPROM and 128 bytes of RAM. It operates within a voltage range of 2.7V to 5.5V and supports clock frequencies up to 10MHz with a 1µs instruction cycle. The device utilizes a 28-pin CSP package (5.5x4.5mm) and includes a modified Harvard architecture for efficient data access. Key peripherals include a 16-bit timer/counter, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic.

Feature Summary

• Modified Harvard architecture enabling direct program memory data access and two-stage pipeline overlap
• Patented EMI reduction technology including low EMI clock circuitry and gradual turn-on output drivers
• Multi-Input Wakeup logic supporting optional interrupts on multiple pins
• Software-selectable I/O configurations including TRI-STATE, push-pull, and weak pull-up modes

Applications

• Low-cost embedded controller applications requiring full feature sets
• Systems necessitating low radiated emissions and electromagnetic interference mitigation
• Battery-powered devices utilizing HALT and IDLE power-saving modes
• Applications requiring high current outputs for driving LEDs or small motors

Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm that the specific ordering suffix matches the required temperature range and package type. Ensure development tools are compatible with the COP8SA family architecture before procurement. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this model when 4KB of non-volatile program memory is required alongside 128 bytes of RAM. The 28-CSP package is suitable for space-constrained designs. Consider the internal R/C oscillator option if external crystal components must be minimized. Verify that the 10MHz maximum speed meets the real-time processing requirements of the target application.

Part Context

This component belongs to the COP8SA family, which serves as a pin-compatible superset of the older COP800 series. It replaces legacy ROM-based controllers in new designs by offering OTP programmability. The family integrates the COP8 core with advanced features like low EMI and power-on reset, targeting cost-sensitive consumer and industrial electronics markets.

Replacement Considerations

COP8SAA7SLB8 and COP8SAB7SLB8 are available within the same family but offer different memory capacities.
