Z86E3116SEG - 8-Bit 16MHz 2KB OTP MCU | Zilog
Référence : Z86E3116SEG ✓ ActifZ86E3116SEG Présentation
A microcontroller is a programmable semiconductor that integrates a CPU, memory, digital I/O, and supporting peripherals into one package. The Z86E3116SEG belongs to the Z8 family of 8-bit microcontrollers, a class commonly used for embedded control because it combines a compact instruction set, dedicated I/O, and low-cost single-power-supply operation. Its larger program and data memories distinguish it from basic 8-pin devices while retaining the straightforward architecture suited to appliance controls, interface logic, and compact embedded systems.
Key features include 2KB of OTP program memory, 125 bytes of RAM, 24 I/O lines, and operation up to 16MHz. Programmable OTP options listed in the device data include an RC oscillator, EPROM protection, auto latch disable, and permanent disable. The 28-pin SOIC package is also available in tube packaging according to the verified distributor data, supporting conventional through-hole board assembly rather than a compact surface-mount land pattern.
The device uses the Z8 CISC architecture and includes an internal oscillator option according to the published specification summary. Its 125-byte RAM supports protocol state, counters, status flags, and short working buffers, while the 2KB OTP program area provides fixed firmware storage after programming. Because OTP memory cannot be electrically rewritten, firmware changes normally require a new programmed device rather than an in-circuit update.
Typical uses include temperature controllers, appliance user interfaces, simple motor-control logic, industrial panel controllers, and embedded peripheral interfaces. In these applications, the 24 available I/O lines can distribute digital signals while the 16MHz operating rate supports time-based control routines and serial communication handling. A designer should still budget memory for interrupts, protocol handling, and application logic.
The primary design constraint is nonvolatile program flexibility: OTP programming makes Z86E3116SEG appropriate for production builds with stable firmware, while applications requiring field updates may prefer a flash-memory MCU. Board layouts must also respect the 28-pin SOIC footprint and provide the required 4.5V to 5.5V supply, decoupling, programming interface, and exposed I/O routing.
This product page consolidates verified distributor specifications, package information, temperature limits, and drop-in comparison data, then adds practical guidance on OTP programming, power-supply design, PCB layout, and selection constraints that are not presented as a complete replacement for the manufacturer datasheet.

Applications typiques
Z86E3116SEG convient pour 6 applications: Appliance Control Panels, Temperature Controller, Simple Motor Control Logic, Embedded Serial Interface, Instrument Front Panel, Fixed-Function Peripheral Controller.
Appliance Control Panels
The Z86E3116SEG fits compact appliance control panels because its 24 I/O lines can support keys, indicators, sensors, and discrete control outputs while the 16MHz Z8 processor handles time-based control logic. The 125-byte RAM provides limited working space for state variables, while 2KB of OTP holds a fixed user-interface and supervisory routine. Its 4.5V-to-5.5V supply range matches a 5V control rail. Because the program memory is OTP, firmware should be validated before production programming.
Recommandé
Temperature Controller
A Z86E3116SEG-based temperature controller can use dedicated I/O for a digital sensor interface, display-control signals, relay drive, and status LEDs. Its 16MHz operating rate provides sufficient instruction throughput for periodic sensing, filtering, and control updates, while the 125-byte RAM can retain a temperature set point, sampled value, and operating state. The -40°C to +105°C listed range supports industrial ambient conditions, although compliance and safety requirements must be verified separately for the finished product.
Recommandé
Simple Motor Control Logic
The Z86E3116SEG can implement a basic motor-control sequencer when the application requires discrete commands rather than a field-oriented control algorithm. Its 24 I/O lines can accommodate limit inputs, start and stop controls, status outputs, and gate-driver signaling, and the 16MHz clock supports deterministic task scheduling. The 2KB OTP program area constrains sophisticated algorithms, so designers should include a dedicated motor driver and verify timing, current limits, and protection behavior at the system level.
Recommandé
Embedded Serial Interface
The Z86E3116SEG can serve as a compact protocol controller when its host interface is a simple UART or bit-banged serial connection. The 16MHz clock leaves processing headroom for framing, checksums, timeouts, and command handling, while the 24 I/O lines provide configurable data, interrupt, and handshake signals. Its 125-byte RAM limits buffer size, so packet lengths and throughput should be checked carefully. OTP is suitable where configuration and firmware are fixed before deployment.
Recommandé
Instrument Front Panel
For an instrument front panel, the Z86E3116SEG can manage button scanning, indicator states, menu flags, and communication with a measurement or processing module. The 24 I/O lines offer enough parallel connectivity for multiple controls and discrete signals, while the 125-byte RAM is suitable for compact menu and status structures. Its 4.5V-to-5.5V operating range simplifies integration with 5V logic. Firmware size should be checked because the available program memory is only 2KB.
Recommandé
Fixed-Function Peripheral Controller
The Z86E3116SEG is appropriate for a fixed-function peripheral that repeatedly executes a short sequence of acquisition, configuration, and control tasks. Its 16MHz clock, 24 I/O lines, and 125 bytes of RAM are sufficient for small protocol handlers and supervisory logic, while 2KB of OTP creates a compact one-time-programmed firmware image. A 28-pin SOIC package supports conventional assembly and inspection. Production teams should preserve program-file traceability because OTP devices cannot be rewritten in the field.

Notes de conception
Design the board for a 4.5V-to-5.5V supply at the Z86E3116SEG pins. Place the required supply bypass capacitor close to the device's power connection and route it with a short ground return to minimize loop area. The supplied data does not specify the manufacturer-recommended capacitor value or ESR, so those values must be obtained from the official datasheet rather than inferred.
Use a 28-pin SOIC land pattern and preserve the manufacturer's recommended pin-1 orientation. Route the programming interface and reset-related signals away from noisy switching nodes, and provide adequate clearance between the MCU and power converters or relay drivers. Although the package is a 28-pin SOIC, no complete pin table was included in the verified data, so the PCB netlist must be checked against the official pinout before fabrication.
Treat the 2KB program memory as one-time programmable rather than field-rewriteable. Validate the complete firmware image, linker map, configuration bits, and boot sequence before programming production units. The available 125 bytes of RAM can be exhausted by stack depth, buffers, and state variables, so include a worst-case memory budget and avoid unbounded recursion or large diagnostic buffers.
Assign the 24 I/O lines according to signal type, separating slower discrete inputs from timing-sensitive or externally driven signals. The internal oscillator and 16MHz operating rate are suitable for conventional embedded tasks, but sensitive analog or communication functions may still require careful grounding and isolation. Do not infer peripheral assignments, alternate functions, or input thresholds from distributor summaries; confirm them in the Zilog datasheet.
The supplied records do not provide a junction-temperature limit, package thermal resistance, or maximum power dissipation, so a complete thermal calculation cannot be performed from the available data. Nonetheless, leave the SOIC unobstructed where practical, avoid placing it directly beside a heat source, and verify the manufacturer's electrical and thermal limits when designing a high-ambient-temperature enclosure.
