Z86E8316PEG - 16MHz 8-Bit MCU with ADC | Zilog
料号： Z86E8316PEG ✓ 量产中Z86E8316PEG 概述
An 8-bit microcontroller is a compact embedded-processing component that combines a CPU core, program memory, data registers, I/O ports, and optional peripherals on one integrated circuit. The Z86E8316PEG belongs to the Zilog Z8 microcontroller family, a hierarchy of 8-bit embedded controllers designed for cost-sensitive control, measurement, appliance-control, and embedded I/O systems. One-time-programmable ROM allows a finished product to receive a fixed application program during manufacturing.
The primary operating characteristics include a 16 MHz clock, 4 KB of OTP program memory, 21 I/O ports, and operation from 4.5 V to 5.5 V. An integrated ADC makes the device suitable for systems that must acquire analog sensor data before processing and forwarding it through digital interfaces. The DIP package also supports conventional through-hole assembly and is useful where production equipment, inspection, or servicing is optimized for pin-inserted components.
The Z8 architecture is designed for compact embedded-control workloads rather than high-throughput computing. Its dedicated I/O resources allow the controller to monitor switches, indicators, actuators, and external analog signals while executing control logic. Because program memory is one-time programmable, firmware is normally written before final programming, which provides a practical mechanism for preventing modification after production programming.
Typical applications include industrial control panels, appliance controllers, instrumentation front ends, digital thermometers, environmental monitors, and compact embedded systems. The ADC supports measurement functions, while the 21 I/O ports provide connections for sensors, displays, relays, and digital communication peripherals. Engineers should verify the ADC resolution, timing, interrupt behavior, and peripheral availability against the manufacturer datasheet before finalizing a new design.
For reliable implementation, use a regulated 5 V supply and confirm that every connected signal remains within the applicable input and output limits. Place suitable bypassing close to the power pins, maintain the required clock and reset conditions, and follow the recommended decoupling layout. Because the package is designed for 4.5 V to 5.5 V operation, a 3.3 V-only system requires an appropriate interface or level-conversion design rather than direct connection.
This product page consolidates the verified operating specifications, package information, sourcing guidance, and design-oriented selection considerations. It also distinguishes the target ordering code from related Z86E8316 family members so engineers can assess temperature-grade and ordering-code changes before committing to a PCB or production BOM.

典型应用
Z86E8316PEG 适用于 6 应用s: Industrial Control Panels, Digital Thermometers, Appliance Control, Environmental Monitoring, Instrumentation Front Ends, LED and Indicator Systems.
Industrial Control Panels
The Z86E8316PEG fits compact industrial control panels that combine digital inputs, status outputs, and analog monitoring. Its 16 MHz Z8 core provides processing capacity for sequencing and control logic, while 21 I/O ports reduce the need for external I/O expansion. The integrated ADC supports monitoring of analog process signals. The 28-pin CDIP package is particularly useful for through-hole assemblies and products expected to undergo conventional insertion or inspection. For a production design, verify the operating-temperature grade, ADC limits, interrupt resources, and unused-pin requirements in the Zilog datasheet before releasing the PCB.
推荐
Digital Thermometers
A digital thermometer can use the Z86E8316PEG to acquire a temperature-sensor signal through its ADC, apply scaling and calibration, and drive a numeric or alphanumeric display. The 16 MHz operating speed supports responsive sampling and display updates, while the 4 KB OTP program memory accommodates fixed conversion, filtering, calibration, and interface routines. Its 21 I/O ports provide connections for display control, buttons, indicators, and alarm signaling. The 4.5 V to 5.5 V operating range aligns with many 5 V instrument architectures, although the power budget should be checked if the display and sensor have different voltage requirements.
推荐
Appliance Control
The Z86E8316PEG is appropriate for fixed-function appliance controllers that coordinate switches, indicators, heaters, relays, or motors through a small embedded control program. Its 4 KB of OTP ROM supports a compact firmware image, and the 21 I/O ports allow a meaningful number of external signals to be managed without making the design dependent on a larger controller. The integrated ADC can supervise analog feedback such as temperature, level, or potentiometer position. Because OTP memory is not user-rewritable in normal operation, the complete firmware must be validated before final programming, and power-loss behavior should be designed around the application's safety requirements.
推荐
Environmental Monitoring
Environmental monitoring stations can use the Z86E8316PEG to digitize sensor outputs, apply thresholds, track operating states, and communicate measurement results through external circuitry. The ADC supports analog acquisition, the 16 MHz core provides sufficient bandwidth for basic signal conditioning and control logic, and 21 I/O ports can handle digital sensors, status LEDs, communication lines, and alarm outputs. The 28-pin CDIP format suits larger instrument platforms assembled with through-hole processes. For battery-powered deployments, confirm whether the device's supply current and 4.5 V minimum input voltage suit the available energy source; the verified listing does not state quiescent-current or sleep-current values.
推荐
Instrumentation Front Ends
The Z86E8316PEG can serve as the controller in a compact instrumentation front end where a measured analog input must be converted, conditioned in firmware, and presented to an operator or downstream system. Its 4 KB OTP memory is suitable for fixed calibration and measurement algorithms, while the 21 I/O ports provide flexibility for display strobes, range selection, status flags, and communications. The 16 MHz clock allows acquisition and control functions to coexist with basic serial communication. Engineers should verify ADC resolution, sample timing, input impedance, reference voltage, and calibration limits before choosing the device for precision measurement, since those detailed values are not stated in the product summaries.
推荐
LED and Indicator Systems
LED-based products can use the Z86E8316PEG for sequencing, brightness-state logic, button handling, fault indication, and control of display elements. The 21 I/O ports offer substantial control flexibility for discrete LEDs, segment displays, and status indicators, while the 16 MHz processor can execute time-based effects without relying on external timers. The ADC may also be used to monitor a dimmer command or analog feedback signal. The 28-pin CDIP package is useful when the product uses through-hole LEDs and connectors rather than a dense surface-mount assembly. Confirm LED drive-current limits and multiplexing requirements in the datasheet, and ensure the supply remains within the 4.5 V to 5.5 V operating range.

设计说明
Design the power rail for the specified 4.5 V to 5.5 V operating range, with margin for supply ripple and startup transients. Place the manufacturer-recommended bypass capacitance directly between the supply and ground pins, using short, low-inductance traces. Do not assume the device can start from a 3.3 V rail; use a suitable regulator or interface arrangement if that is the only available source.
Use the Zilog 28-pin CDIP mechanical drawing when defining drill locations, pad diameters, and silkscreen. Preserve access to every pin for inspection and repair, and place input, reset, and clock components close to their associated device pins. Because the package is through-hole, confirm the assembly process's insertion depth and soldering profile rather than applying a surface-mount reflow profile.
Program the OTP only after the complete firmware and all calibration constants have been validated, because OTP cannot be revised by ordinary in-circuit reprogramming. Check the supply ramp against reset requirements, configure unused pins exactly as directed by the datasheet, and verify ADC source impedance and acquisition timing. These steps prevent programming scrap and unreliable analog measurements.
Do not interchange Z86E8316 ordering codes solely because they share the Z86E8316 family name. A suffix can change package construction, temperature grade, or ordering compliance. Before substituting PAG, PEC, PEF, PEJ, or PAJ for PEG, compare the exact package drawing, pin table, environmental limits, and lifecycle status in the applicable Zilog documentation.
合规信息
The PEG ordering suffix indicates the RoHS-compliant configuration. REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status were not explicitly documented for the exact ordering code.
