Z86E3116PSG - 16MHz 8-Bit Z8 MCU | Zilog
Référence : Z86E3116PSG ✓ ActifZ86E3116PSG Présentation
An 8-bit microcontroller is a compact embedded processor designed to execute control logic, monitor digital inputs, and operate peripherals using a relatively small instruction set and memory footprint. Within the embedded-control hierarchy, it belongs to the Z8 family of 8-bit microcontrollers and combines a CPU core, nonvolatile OTP program memory, RAM, timers, and general-purpose I/O in one integrated circuit.
The Z86E3116PSG provides a 16 MHz operating frequency, a 2K x 8 OTP architecture, and 24 I/O pins. Its on-chip resources include two 8-bit timers, a power-on reset function, and a watchdog timer. OTP memory allows firmware to be programmed once during manufacturing or commissioning, making the device suitable for fixed-control products in which field updates are unnecessary.
The Z8 architecture supports economical embedded-control designs while keeping the external component count relatively low. With 24 I/O pins, the device can directly interface with switches, indicators, relays, sensors, and discrete logic. Two timers support periodic tasks, input timing, debouncing, or basic event counting, while the watchdog timer provides a mechanism for recovering from unexpected program flow faults.
Typical uses include appliance controls, small industrial controllers, building-control modules, simple sensor interfaces, LED and lighting controllers, and compact embedded products requiring a DIP footprint. The through-hole DIP package is particularly useful for prototypes, low-to-medium-volume products, and assemblies where socketed or manually inserted construction is preferred.
Designers should verify each signal's electrical limits, oscillator requirements, programming method, and timing behavior against the manufacturer datasheet. Because OTP memory cannot be erased, firmware validation and manufacturing-programming controls are especially important. The 28-pin DIP footprint also requires adequate board space, connector accessibility, and mechanical clearance around the device.
This page combines the Z86E3116PSG's principal memory, timing, I/O, and packaging characteristics with a focused drop-in alternative assessment, practical implementation guidance, and an application-oriented selection framework for compact Z8-based control designs.

Applications typiques
Z86E3116PSG convient pour 6 applications: Appliance and Kitchen-Control Modules, Small Industrial Sensor Interfaces, LED Lighting and Display Control, Building Control and Access Modules, Compact Instrumentation Control, Prototype and Educational Controller Boards.
Appliance and Kitchen-Control Modules
The Z86E3116PSG fits compact appliance controllers that combine push-button inputs, status indicators, relays, and small timing sequences. Its 24 general-purpose I/O pins reduce the need for an external I/O expander, while the two 8-bit timers can support button debouncing, motor timing, or periodic control tasks. The 16 MHz Z8 core provides adequate response for straightforward fixed-function logic, and the 3.5 V to 5.5 V operating range accommodates common embedded rails. Because program memory is OTP, the firmware should be fully qualified before production programming.
Recommandé
Small Industrial Sensor Interfaces
The Z86E3116PSG is suitable for compact sensor-conditioning and discrete-control modules that read switches or digital sensors and activate alarms or relays. Its 24 general-purpose I/O pins provide direct connections for multiple digital channels, while the watchdog timer helps recover the controller after unexpected execution faults. The two 8-bit timers can support input timing, pulse counting, and scheduled sampling. The 16 MHz operating rate suits short deterministic control loops, and the DIP package simplifies prototype assembly and through-hole manufacturing for low- to medium-volume equipment.
Recommandé
LED Lighting and Display Control
The Z86E3116PSG can manage addressable or grouped LED indicators in signs, control panels, and status displays when the chosen LED driver interface is compatible with its timers and I/O. Its 24 I/O pins can distribute multiple enable, segment, or data signals, while two timers support refresh timing, pulse generation, and button feedback. The 16 MHz clock provides useful timing margin for modest display tasks, and OTP firmware supports permanently configured lighting sequences. Current limits on each I/O and the external driver interface must be checked so the MCU does not directly exceed individual-pin drive limits.
Recommandé
Building Control and Access Modules
The Z86E3116PSG is applicable to compact building-control modules that monitor door, call, or presence inputs and operate indicators, locks, or other discrete outputs. Twenty-four general-purpose I/O pins allow a single controller to handle several wired interfaces, and the watchdog timer provides useful supervision for unattended equipment. The 3.5 V to 5.5 V range supports standard low-voltage control rails. The 2 KB OTP limit constrains program complexity, so concise firmware is preferable for multi-function access products. Security-sensitive or battery-backed installations require separate evaluation of power consumption and failure modes.
Recommandé
Compact Instrumentation Control
The Z86E3116PSG can serve as the supervisory controller in compact test or measurement equipment where the task is primarily digital. Its 24 I/O pins can initiate measurements, operate mode controls, monitor completion signals, and drive status lamps. The two 8-bit timers support measurement windows and periodic housekeeping, while the 16 MHz core handles straightforward sequencing. For precision analog measurement, a dedicated ADC should perform acquisition and feed digital results to the MCU. The DIP package is convenient for instrument prototypes, although final high-volume products may use a smaller surface-mount package after circuit stabilization.
Recommandé
Prototype and Educational Controller Boards
The Z86E3116PSG works well in educational and prototype controller boards because its 28-pin DIP footprint is easy to install, inspect, and replace. The through-hole package supports conventional breadboards, perfboards, sockets, and manual assembly, reducing the need for specialized soldering equipment. Its 24 I/O pins provide enough connections for switches, LEDs, displays, and basic interface experiments, while the 16 MHz clock and two timers support interactive demonstrations. OTP programming is suitable for repeatable teaching fixtures, although it makes rapid firmware iteration less convenient than flash-based alternatives.

Notes de conception
Treat OTP programming as a one-way manufacturing step. Validate the complete firmware image, bootloader behavior if applicable, interrupt vectors, timing constants, and all I/O assignments before programming production units. Keep a master binary and programming records for each device lot. If frequent firmware changes are foreseeable, redesign around a flash-memory MCU because repeated field updates are impossible with the Z86E3116PSG's 2 KB OTP architecture.
Reserve the full 28-pin DIP footprint with 0.600-inch row spacing and maintain access to every programming-related pin. Decouple the supply close to the device and route clocks away from switching nodes and high-current relay traces. If the board includes relays, motors, or solenoids, use separate return paths and flyback protection rather than allowing transient current to flow through MCU ground traces. Confirm clearance around the chip body and socket to avoid mechanical interference with adjacent components.
Operate the device only within the specified 3.5 V to 5.5 V range, including startup and transient conditions. Use the datasheet's recommended decoupling values and account for voltage drop across long supply paths. The two 8-bit timers and 24 I/O lines allow the controller to remain active continuously, so the system power budget should include MCU consumption alongside sensors, interface circuits, and indicator drivers. Do not calculate external-load current from the MCU supply requirement or assume an I/O pin can continuously drive a load without checking its drive limits.
Do not treat the 24 general-purpose I/O count as 24 simultaneously usable peripheral pins. Some pins are dedicated to power, ground, clock, reset, or programming, and several may have alternate functions. Build the firmware pin map from the manufacturer's pin-description table and verify that oscillator, timer, interrupt, and programming assignments do not conflict. When replacing Z86E3116PSG with Z86E3016PSG, recheck every affected connection because the alternative has eight fewer general-purpose I/O lines.
