COP8SAC720M8X/NOPB Übersicht
The COP8 (Controller Oriented Processor) family is a mature 8-bit CISC architecture originated by National Semiconductor and now maintained by Texas Instruments. COP8 microcontrollers are accumulator-based Harvard-architecture devices featuring a rich instruction set, multiple addressing modes, and integrated peripherals such as timers, A/D converters, and serial interfaces. They are widely deployed in white-goods, appliance, industrial-control, and consumer-electronics applications where deterministic behavior, low EMI, and OTP-based code security are valued. The COP8SAC720M8X/NOPB is the OTP variant of the COP8SA family, intended for prototyping and low-to-medium volume production.
Key features include 16 GPIO pins, an 8-bit accumulator-based CPU core, on-chip power-on reset eliminating external reset circuitry, and a wide operating voltage range of 2.7 V to 5.5 V. The 20-SOIC package measures 7.50 mm in body width, and the device operates over the industrial -40 °C to +85 °C temperature range. The integrated oscillator with low-EMI feature reduces electromagnetic emissions in noise-sensitive applications.
The COP8SAC720M8X/NOPB is pin-compatible with other COP8SA family members including COP8SAB720M8 and COP8SAC744M8, enabling designers to migrate between memory sizes without PCB rework. It supports in-system programming via TI's development toolchain and is supported by the COP8-ICE emulator. According to the manufacturer datasheet, the device includes a multi-source interrupt controller, two 16-bit timers, and a UART-compatible serial port.
Typical applications include appliance control boards, HVAC thermostat controllers, security alarm panels, battery charger control, and small home-automation sensor nodes. The OTP memory provides one-time programmability for low-volume or secure code storage, eliminating the need for external EEPROM in many designs.
When designing with this part, ensure the OTP programming voltage and timing requirements are observed during code development. The COP8 instruction set is non-standard, so engineers must use the TI COP8 assembler and toolchain for code development.

Typische Anwendungen
COP8SAC720M8X/NOPB ist geeignet für 6 Anwendungs: White-Goods Appliance Control, HVAC Thermostat Controller, Security Alarm Panel, Battery Charger Controller, Industrial Sensor Node, Consumer Remote Control / IR Emitter.
White-Goods Appliance Control
The COP8SAC720M8X/NOPB's 4 KB OTP memory, 16 GPIO pins, and integrated power-on reset make it a strong fit for washing-machine, dishwasher, and microwave-oven control boards. The on-chip low-EMI oscillator reduces conducted emissions that must pass appliance EMC standards such as EN 55014, while the 20-SOIC package is hand-solderable for low-volume white-goods production. Compared with flash MCUs, the OTP memory locks the firmware against in-field tampering - a useful property for warranty and safety-certified appliances. Engineers typically allocate ~3 KB of the 4 KB program store to the main control loop and timing routines, leaving ~1 KB for user-interface handling.
Empfohlen
HVAC Thermostat Controller
Wall-mounted HVAC thermostats require low cost, deterministic real-time response, and immunity to brown-outs on long thermostat wiring - all satisfied by the COP8SAC720M8X/NOPB. The 10 MHz COP8 core runs the temperature-sampling loop and hysteresis-control state machine within a few hundred microseconds, while the 128-byte RAM comfortably holds the setpoint, filtered sensor value, and relay-state variables. The integrated power-on reset avoids a discrete reset IC in the compact thermostat housing. Operating from -40 °C to +85 °C industrial range, the part survives unconditioned attic and basement environments.
Empfohlen
Security Alarm Panel
Security alarm panels favor OTP memory for code security, and the COP8SAC720M8X/NOPB's 4 KB program store accommodates zone-monitoring, arm/disarm state machines, and keypad-debounce routines. The 16 GPIO pins map cleanly onto 8-zone inputs plus 4 status LEDs, a piezo driver, and a keypad interface without external muxing. The integrated low-EMI oscillator helps the panel pass FCC Part 15 radiated-emission limits. COP8's multi-source interrupt controller prioritizes PIR-sensor and smoke-detector interrupts above keypad scanning, which is critical for life-safety response latency.
Empfohlen
Battery Charger Controller
Lead-acid and NiMH charger controllers rely on accurate timing of charge, absorption, and float phases - the COP8SAC720M8X/NOPB's two 16-bit timers handle CC/CV state transitions within ±1 % accuracy. The 4 KB OTP memory stores the charging algorithm, temperature-compensation curves, and fault-handling routines. Operating from 2.7 V to 5.5 V, the MCU can be powered directly from a 5 V USB rail or a buck-derived auxiliary supply. OTP code storage prevents end-user firmware modification, which is important for UL-listed charger products.
Empfohlen
Industrial Sensor Node
Cost-sensitive industrial 4-20 mA sensor transmitters benefit from the COP8SAC720M8X/NOPB's small footprint and integrated POR. The 10 MHz CPU performs ADC sampling, linearization, and HART-protocol framing, while the UART-compatible serial port drives the HART modem interface. The wide -40 °C to +85 °C operating range and 20-SOIC's mechanical robustness suit factory-floor deployment. The 128-byte RAM is sufficient for the HART receive/transmit buffers and the calibration constants table.
Empfohlen
Consumer Remote Control / IR Emitter
IR remote controls, learning remotes, and small consumer appliances use the COP8SAC720M8X/NOPB for its low cost, very low standby current, and integrated oscillator. The 16 GPIO pins drive an IR LED via a MOSFET, scan a 4x4 keypad matrix, and blink status LEDs without external glue logic. OTP memory locks the IR protocol code against cloning. The COP8's accumulator-based architecture executes the IR carrier-generation loop with deterministic timing, critical for NEC, RC5, and SIRC protocol compliance.

Wichtigste Unterscheidungsmerkmale

Designhinweise
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 20) and a 10 µF bulk capacitor on the supply rail within 25 mm of the device. The integrated power-on reset monitors VDD but does not suppress supply ripple below the POR threshold - add bulk capacitance if the supply is derived from a long cable or a switching regulator. For battery-powered designs, leverage the COP8SAC720M8X/NOPB's HALT/IDLE modes to drop quiescent current; verify wake-up timing against the 32 kHz internal oscillator tolerance before finalizing power-budget calculations.
OTP memory can be programmed exactly once - any subsequent write attempts are blocked. During development, use a windowed EPROM version of the COP8SA family or a socketed COP8-ICE emulator to iterate firmware before committing to the production OTP part. Verify programming voltage (typically 12.5 V on the VPP pin) and timing per the COP8SA datasheet programming section; under-programmed cells can cause intermittent failures in the field that are difficult to diagnose.
Keep the OSC1/OSC2 crystal traces short (under 5 mm) and surrounded by a ground guard ring to reduce EMI pickup. Place the crystal and load capacitors on the same layer as the MCU to avoid via-induced parasitic inductance. The COP8SAC720M8X/NOPB's low-EMI oscillator feature helps pass EN 55022 / FCC Part 15, but a clean PCB layout is still required - especially avoid routing high-frequency switching signals near the oscillator traces.
Compliance-Informationen
