COP8SAA7SLB8

Overview

The COP8SAA7SLB8 is an 8-bit CMOS microcontroller from the COP8SA family, featuring 1KB (1K x 8) One-Time Programmable (OTP) program memory and 64 bytes of RAM. It operates within a voltage range of 2.7V to 5.5V and supports clock speeds up to 10MHz using an internal R/C oscillator or external crystal. The device utilizes a 28-pin CSP package measuring 5.5x4.5mm and includes 24 I/O pins with high current output capabilities.

Feature Summary

• Integrated low electromagnetic interference design utilizing gradual turn-on output drivers and internal smoothing filters.
• Versatile instruction set optimized for code efficiency with single-byte, single-cycle execution capabilities.
• Flexible software-configurable I/O ports supporting push-pull, tri-state, and weak pull-up modes.
• Built-in peripheral features including a 16-bit timer with PWM output and MICROWIRE/PLUS serial interface.

Applications

• Low-cost embedded control systems requiring minimal external components
• Battery-operated devices utilizing power-saving HALT and IDLE modes
• Applications necessitating reduced radiated emissions in compact form factors

Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm package integrity upon receipt, specifically checking for damage to the small outline CSP leads.
