Product details
Overview
COP8SGE5 from Texas Instruments is an 8-bit CMOS ROM-based microcontroller with 8k program memory, 256 bytes of on-board RAM, two analog comparators, full-duplex USART, and three 16-bit timers - used in industrial control systems requiring low EMI, high-current I/O, and secure firmware storage.
For engineers reviewing the COP8SGE5 datasheet, COP8SGE5 pinout, COP8SGE5 application, or COP8SGE5 equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options for embedded system design and replacement sourcing.
Technical Context
The COP8SGE5 implements a modified Harvard architecture with single-cycle instruction execution (77% of instructions), enabling efficient table lookups and subroutine handling via software stack. Its clock subsystem supports crystal, external, or internal R/C oscillation with user-selectable bias resistor and clock monitor logic.
Peripheral integration includes MICROWIRE/PLUS™ (SPI-compatible) serial interface, multi-input wakeup logic across eight pins, and two analog comparators with ±5 mV input offset and 600 ns response time - all operating within 2.7 V to 5.5 V supply range and −40°C to +125°C temperature grade.

Applications
| Industrial Motor Control | Smart Sensor Interface |
|---|---|
|
Use Scenario: Closed-loop DC motor speed regulation using PWM output and analog feedback. IC Role / Device Role / Timing Role: COP8SGE5 executes PID algorithm, generates 16-bit PWM via T1/T2, reads analog comparator outputs as zero-crossing detectors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| COP8SGR5 | 32k ROM, 512-byte RAM, same peripherals and pinout; higher memory density and extended I/O flexibility | Suitable for firmware upgrades requiring larger code space or additional data buffers without layout change | Select when application firmware exceeds 8k or requires >256-byte RAM for real-time data logging |
| COP8SGE7 | 8k OTP EPROM instead of ROM; identical timing, I/O, and peripheral set; windowed PDIP/PLCC available for development | Enables iterative firmware development and field updates where ROM mask cost is prohibitive | Choose for prototyping, low-volume production, or applications needing post-manufacture firmware revision |
Compared with COP8SGE5, COP8SGR5 offers scalable memory for complex control algorithms, while COP8SGE7 provides reprogrammability without sacrificing electrical or mechanical compatibility - both maintain identical instruction timing, peripheral register maps, and thermal specifications.

FAQ
What is the maximum clock frequency supported by COP8SGE5?
COP8SGE5 supports a maximum CKI input frequency of 15 MHz, yielding a 0.67 μs instruction cycle time at 5.5 V supply. At lower voltages (2.7 V–4.5 V), the maximum clock rate reduces to 4 MHz–10 MHz depending on operating conditions, as specified in the AC Electrical Characteristics section of SNOS516E.
Does COP8SGE5 include on-chip oscillator circuitry?
Yes, COP8SGE5 integrates an internal R/C oscillator and supports crystal/resonator operation with on-chip bias resistor. The device can operate without external timing components in crystal mode, and the oscillator configuration is selected via software-controlled bits in the ECON register.
How many I/O pins does COP8SGE5 provide in its 40-pin PDIP package?
In the 40-pin PDIP package, COP8SGE5 provides 36 usable I/O pins - distributed across ports C (8), G (8), L (8), and F (8), plus two dedicated pins (CKI and RESET). VCC and GND are power-only pins and do not contribute to I/O count.
Can COP8SGE5 operate at 3.3 V supply voltage?
No - COP8SGE5 is rated for 2.7 V to 5.5 V operation, but its DC and AC characteristics are only guaranteed down to 2.7 V. At 3.3 V, the device meets all specifications including 10 MHz operation, HALT current <4 μA, and comparator functionality, as confirmed in the −40°C to +85°C electrical tables of SNOS516E.
Is COP8SGE5 pin-compatible with COP8SGE7?
Yes - COP8SGE7 is a 100% form-fit-function compatible OTP version of COP8SGE5, sharing identical pinout, package options, electrical specifications, and peripheral register mapping. The only functional difference is programmable memory type (ROM vs. OTP EPROM).
