Key Features
- 8-bit COP8 core operating at up to 10 MHz with 1KB OTP program memory for simple, cost-effective dedicated embedded control applications
- 20-pin PDIP package enables through-hole assembly and easy prototyping on standard breadboards without specialized SMT equipment
- OTP (One-Time Programmable) memory provides secure, tamper-resistant program storage for high-volume production runs where field reprogramming is not required
Applications
COP8SAA520N8XXX is designed for simple embedded control tasks such as appliance timers, keypad controllers, and dedicated motor sequencing circuits where an 8-bit microcontroller with 1KB program memory and 10 MHz operation is sufficient. Its 20-pin PDIP form factor suits through-hole prototype boards and legacy PCB replacements in existing product lines. The OTP memory makes it cost-effective for high-volume consumer goods and industrial control modules where firmware is fixed at manufacturing time.

Frequently Asked Questions
What program memory type and size does COP8SAA520N8XXX provide, and how does OTP affect production?
COP8SAA520N8XXX contains 1KB of OTP (One-Time Programmable) memory, meaning the 8-bit program is written once during manufacturing and cannot be erased or updated in the field. This reduces per-unit memory cost versus EEPROM-based microcontrollers and suits high-volume appliance or toy production where firmware is locked before shipment.
At 10 MHz clock frequency, what kinds of control tasks can COP8SAA520N8XXX perform reliably?
At up to 10 MHz with an 8-bit data bus, COP8SAA520N8XXX comfortably handles keypad scanning, LED multiplexing, timer-based PWM generation, simple serial communication, and relay sequencing tasks. It does not include an ADC or DMA, so analog sensing requires external ADC chips, but pure digital control loops with sub-100 µs response times are well within its capability.
Is COP8SAA520N8XXX still a viable choice for a new design in 2024, or should designers migrate to a newer MCU?
COP8SAA520N8XXX has a YTEOL (Years To End Of Life) of 0, indicating it is at or near end-of-life status. For new designs requiring 8-bit microcontrollers, Texas Instruments MSP430 series or Microchip PIC16 series offer more I/O, integrated ADC, lower power, and longer product life at comparable cost. COP8SAA520N8XXX remains suitable only for legacy system repair and existing PCB replacement.
What assembly process does the 20-pin PDIP package of COP8SAA520N8XXX support?
The 20-pin PDIP (R-PDIP-T20) package uses 2.54 mm through-hole pin spacing, compatible with wave-soldering production lines and manual soldering for prototyping on standard 0.1-inch pitch breadboards and perfboards. No SMT reflow equipment is needed, which simplifies rework and repair for low-volume or legacy production environments.
