Z86E3116PEG - 8-Bit 16MHz 2KB OTP MCU | Zilog
料号： Z86E3116PEG ✓ 量产中Z86E3116PEG 概述
An 8-bit microcontroller is a compact embedded-control IC used to execute firmware, read inputs, and control outputs in dedicated electronic systems. The Z86E3116PEG belongs to the microcontroller hierarchy, combining a Z8 processor core, program memory, RAM, digital I/O, and embedded timing functions. Its one-time-programmable architecture is intended for products where firmware is written during manufacturing and does not need to be updated in the field.
Key device characteristics include 16MHz operation, 24 general-purpose I/O lines, 125 bytes of RAM, and programmable OTP options identified in the source data as RC oscillator, EPROM protection, auto latch disable, and permanent settings. Integrated features reported by the Microchip USA product listing include a power-on reset and watchdog timer, providing basic startup supervision and recovery support for embedded control firmware.
The device uses a 5V-class supply range of 4.5V to 5.5V. Its 28-DIP package provides through-hole mounting and a 0.600-inch body width, making it appropriate for legacy-style control boards, industrial controllers, appliance controllers, and compact embedded systems assembled with conventional through-hole techniques. Because the available product information does not include the complete datasheet pin map, individual signal assignments cannot be reproduced safely here.
Typical application roles include simple sequencing and logic control, switch and relay management, status-indicator control, small industrial equipment interfaces, and dedicated appliance controllers. In each case, firmware stored in the 2KB OTP program memory determines the control behavior, while the 24 I/O lines provide connections to external sensors, switches, and actuators.
Designers should account for the 4.5V to 5.5V supply requirement, confirm that the board uses the 28-pin DIP footprint, and validate timing, oscillator, reset, and watchdog behavior against the manufacturer datasheet before production release. The available data identifies the oscillator as internal, but its frequency range and detailed configuration requirements are not stated.
This page consolidates verified distributor specifications, current sourcing information, package details, application guidance, and explicit data gaps. It also distinguishes verified facts from unspecified parameters, helping engineers evaluate the Z86E3116PEG without mistaking generic cross-reference tools for evidence of a pin-compatible replacement.

典型应用
Z86E3116PEG 适用于 6 应用s: Appliance Control, Industrial Switch Sequencing, LED and Indicator Control, Sensor Interface and Logic Hub, Security and Access Controller, Legacy Through-Hole Embedded Products.
Appliance Control
The Z86E3116PEG fits compact appliance controllers that use fixed firmware to coordinate switches, indicators, and actuators. Its 24 I/O lines provide ample digital connections for control inputs and outputs, while 125 bytes of RAM supports modest state variables and 2KB of OTP program memory accommodates a focused control routine. Running at up to 16MHz provides more timing margin than many simple switch-sequencing tasks require. The 28-DIP through-hole package also simplifies assembly on appliance boards using conventional insertion. Engineers should verify timing, reset behavior, and watchdog configuration against the manufacturer documentation before fixing the firmware.
推荐
Industrial Switch Sequencing
The Z86E3116PEG can serve as a dedicated sequencing controller for industrial switch panels and relay interfaces when the required behavior fits within 2KB of OTP firmware. Its 24 I/O lines can distribute control signals across multiple channels, and the integrated watchdog timer provides a recovery mechanism for firmware stalls. The 4.5V to 5.5V operating range is suitable for a 5V control rail, although the verified material does not establish the operating-temperature limits needed for every industrial environment. Qualification for a specific machine environment must therefore be confirmed from the original Zilog documentation.
推荐
LED and Indicator Control
For LED panels, status indicators, and discrete display-control boards, the Z86E3116PEG provides 24 I/O lines and a 16MHz maximum operating frequency for coordinated lighting sequences and state logic. Its 2KB OTP program memory is appropriate for fixed timing tables and simple control patterns, while 125 bytes of RAM can hold counters, flags, and debounce state. The 28-DIP package allows direct through-hole placement on larger control boards. Because LED loads may require switching transistors, the engineer should use the I/O pins for drive logic rather than assuming every indicator can be connected directly.
推荐
Sensor Interface and Logic Hub
The Z86E3116PEG can act as a small logic hub between discrete sensors and downstream actuators in a compact embedded system. Its 24 I/O lines accommodate digital sensor inputs, mode-control outputs, and communication or interface signals when their electrical requirements are compatible with the microcontroller. The 16MHz Z8 core supports event sequencing, filtering, and state management, although the 125-byte RAM limit requires disciplined buffer allocation. Firmware should avoid unnecessary blocking delays and use the watchdog appropriately. The supplied data does not characterize every I/O pin, so signal compatibility must be checked against the complete pinout.
推荐
Security and Access Controller
The Z86E3116PEG is appropriate for simple access-control subsystems that require fixed logic, discrete inputs, and controlled outputs rather than intensive communications. Its power-on reset supports deterministic startup, while the watchdog timer can help recover from a stalled control loop. The 2KB OTP memory limits application complexity and makes the architecture well suited to firmware that is committed during manufacturing. For security-sensitive products, engineers must add appropriate physical and logical protections because OTP alone does not establish secure key storage. The exact I/O assignments and programming safeguards must be verified in the manufacturer documentation.
推荐
Legacy Through-Hole Embedded Products
The Z86E3116PEG is well matched to legacy-style through-hole products that need a modest, deterministic embedded controller rather than a high-pin-count processor. Its 28-DIP package, 5V supply range, 16MHz operation, and 24 I/O lines support established manufacturing processes and straightforward schematic organization. The architecture is useful for dedicated equipment controls where 2KB OTP and 125 bytes of RAM are sufficient. A careful review should confirm oscillator configuration, reset timing, watchdog behavior, and unused-pin requirements. Since the supplied information omits the complete pinout and operating-temperature limits, prototypes should not be released until those details are checked in the manufacturer documentation.

设计说明
Confirm the physical footprint before layout because the verified package is a 28-DIP, 0.600-inch (15.24mm) through-hole device. The supplied data does not include a complete pin map, so preserve a straightforward DIP-28 land pattern and verify every power, ground, programming, clock, and I/O connection against the manufacturer pin configuration. Do not derive assignments solely from the fact that the device has 24 I/O lines.
Design the board supply for 4.5V to 5.5V and account for startup and load-current behavior in the complete electrical characteristics. The verified data establishes the voltage range but does not provide input-current, output-driver-strength, or absolute-maximum limits. Use the manufacturer guidance for decoupling and signal-level compatibility instead of assuming 3.3V peripherals can connect directly to all I/O pins.
One-time-programmable memory should be treated as a one-time programming decision. Validate the complete image, boot path, and OTP option settings in engineering samples before production programming. The source data names RC oscillator, EPROM protect, auto latch disable, and permanent settings as programmable options, but their exact programming procedure and irreversible consequences must be read from the official programming documentation.
The available verified data does not state the junction-temperature rating, thermal resistance, or power dissipation under maximum clock and I/O activity. Consequently, no defensible thermal estimate can be made from the supplied information. For enclosed systems, use the manufacturer electrical and thermal data to determine whether the 28-DIP package needs spacing, airflow, or board-level heat dissipation.
合规信息
The verified LCSC listing identifies Z86E3116PEG as RoHS compliant. No verified REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification statements were provided. AEC-Q100 is not applicable because this product is an 8-bit microcontroller rather than an automotive-qualified device.
