Z86E0812PEG - 8-Bit 12MHz OTP Microcontroller | Zilog
部品番号: Z86E0812PEG ✓ 生産中Z86E0812PEG 概要
An 8-bit microcontroller is a programmable semiconductor containing a processor core, memory, I/O ports, and supporting peripherals on one integrated circuit. The Zilog Z8 family belongs to the broader embedded-controller hierarchy that includes microcontrollers, embedded processors, and semiconductors. Compared with a general-purpose processor, this device targets smaller control loops where cost, simplicity, deterministic peripheral access, and board area are more important than complex computation or high memory bandwidth.
Key verified specifications include a 12 MHz maximum clock speed, 2 KB of OTP program memory, 14 I/O ports, and a 4.5 V to 5.5 V operating supply range. Its operating temperature spans -40°C to +105°C, making it suitable for industrial-temperature equipment when the associated system design and qualification requirements are satisfied. The RoHS designation identifies the part as compliant with the supplied RoHS listing, while other regulatory classifications remain unconfirmed in the available data.
The device uses the Z8 architecture described in the available product listings as an eZ8 CISC microcontroller. One-time-programmable memory is intended for firmware that does not require later field rewriting, helping control production complexity when the final program is known before deployment. The 14 I/O pins provide interfaces for digital inputs, output control, or mixed peripheral functions, while the 18-pin PDIP format supports conventional through-hole assembly and prototyping.
Typical applications include small industrial controllers, sensor-interface modules, building-control products, appliance-control boards, and compact embedded instruments. The 12 MHz clock is appropriate for moderate-speed digital sequencing, while the 14 available I/O ports can connect switches, indicators, relays, and discrete sensing components. Because the part has 2 KB of OTP rather than large RAM or Flash, firmware should be sized carefully and peripheral-heavy tasks delegated to dedicated devices when necessary.
The primary design consideration is validating the exact pin assignments, oscillator requirements, reset behavior, and programming procedure against the official manufacturer documentation before layout release. Designers should also confirm current consumption and timing behavior for the selected external clock and operating conditions, because those values were not established by the supplied verification data. DIP packaging requires adequate insertion clearance, mechanical support, and protection from electrostatic discharge during handling.
This product page consolidates verified distributor specifications, lifecycle information, package details, commercial availability links, and practical application guidance. It also distinguishes verified Zilog family drop-in options from unverified cross-brand replacements so engineers can make a sourcing decision without treating general cross-reference tools as proof of pin and firmware compatibility.

主な用途
Z86E0812PEG の用途: 6 件s: Small Industrial Control Boards, Building and HVAC Control, Appliance and Equipment Controllers, Sensor Interface Modules, LED Lighting Sequencing, Compact Communication and Data Modules.
Small Industrial Control Boards
The Z86E0812PEG fits compact industrial-control boards that coordinate discrete sensors, relays, indicators, and push-button inputs. Its 14 I/O ports provide a practical interface count for digital control, while the 12 MHz Z8 core handles sequential logic and timing tasks. The verified -40°C to +105°C operating range supports industrial-temperature product development, although the final enclosure, power supply, and production testing must satisfy the system requirements. Because the device contains only 2 KB of OTP program memory, firmware should be modular and avoid unnecessary tables or duplicated routines. The 4.5 V to 5.5 V supply range also makes the part suitable for regulated 5 V control boards that already provide stable rail quality.
おすすめ
Building and HVAC Control
Z86E0812PEG is appropriate for building-control products that combine a small number of digital inputs with relay or indicator outputs. Its 14 I/O ports can reduce the need for a separate expander in a compact controller, and the 12 MHz clock provides sufficient control bandwidth for event sequencing and basic debounce routines. The 2 KB OTP capacity favors deterministic firmware rather than large application frameworks. The verified 4.5 V to 5.5 V operating range fits a regulated 5 V HVAC controller, while the -40°C to +105°C specification supports designs intended for heated equipment rooms. Designers should still account for inductive loads, contactor transients, and the need for isolation or protective circuitry.
おすすめ
Appliance and Equipment Controllers
The Z86E0812PEG can serve as the primary controller in a small appliance or laboratory instrument where switches, status lamps, and discrete actuator commands are controlled by a compact program. A 12 MHz Z8 processor is adequate for predictable state-machine control, while 14 I/O ports leave sufficient interface capacity for panel inputs and outputs. The 18-pin PDIP package is particularly convenient for prototypes, hand-built instruments, and low-volume through-hole assemblies. Its 2 KB OTP memory requires the manufacturer programming process to be planned before production. Firmware updates after deployment are not possible with OTP, so functional validation, revision control, and programming traceability are essential engineering considerations.
おすすめ
Sensor Interface Modules
Z86E0812PEG is suitable for a sensor-interface module that converts discrete digital sensor states into a higher-level control or alarm output. Fourteen I/O ports allow multiple inputs to be sampled while outputs drive status indicators or interface logic, and the 12 MHz operating speed supports responsive sampling and debounce routines. The device should be paired with external analog conditioning when measurements exceed its digital input capabilities. Since no ADC resolution was confirmed in the supplied records, this application is restricted to digital sensors or external converters. The 4.5 V to 5.5 V supply range suits regulated 5 V sensing modules, and the industrial temperature listing supports use in equipment where ambient conditions are controlled.
おすすめ
LED Lighting Sequencing
The Z86E0812PEG can implement compact LED sequencing, status indication, and simple decorative lighting controllers. Its 14 I/O ports allow multiple indicator channels to be managed from one controller, and the 12 MHz clock is more than adequate for timed patterns and button-driven effects. The 2 KB OTP program store is sufficient for compact lookup tables and state logic when the firmware is written efficiently. A 5 V rail within the verified 4.5 V to 5.5 V range simplifies integration with common LED driver circuits. Engineers must calculate the aggregate current from attached LEDs and drivers, because the verified data does not establish individual or total port-drive ratings. transistor drivers or a dedicated LED driver should be used when the load exceeds safe GPIO limits.
おすすめ
Compact Communication and Data Modules
Z86E0812PEG can support small embedded communication modules that coordinate a limited number of digital interface signals when the main protocol is handled by a companion IC. The controller can manage resets, mode selection, status indicators, and configuration GPIO while the 12 MHz Z8 core performs local sequencing. Its 14 I/O ports are useful for peripheral selection and monitoring, while the 2 KB OTP memory keeps local firmware compact. Because the verified records do not identify an internal UART, SPI, or other communications peripheral, the specific interface arrangement must be confirmed from the official datasheet. A qualified communications companion such as a UART or transceiver should be selected only after those pin-function requirements are established.

設計ノート
Design the supply rail for the verified 4.5 V to 5.5 V operating range and verify startup, ripple, and transient behavior under worst-case system conditions. Do not infer absolute maximum voltage or port-current limits from the nominal range. Place the local supply decoupling directly beside the appropriate device pins using the official reference layout, and keep noisy switching or relay-driver return currents out of the controller ground path.
Use the official Zilog pinout rather than a distributor package illustration when assigning oscillator, reset, programming, and I/O signals. The supplied sources identify an 18-pin PDIP but do not publish the individual pin names. Confirm the pin-1 orientation, oscillator connection, programming interface, and exposed test requirements against the manufacturer datasheet before releasing a PCB or wiring schematic.
Plan the OTP programming operation early because the Z86E0812PEG provides one-time-programmable memory rather than field-rewritable Flash. Validate the complete firmware image, programming voltage, timing, and device identification in a pre-production run. A small production quantity of programmed devices should be tested and retained as known-good references before committing the remaining inventory.
The through-hole PDIP format requires adequate board edge clearance, connector space, and mechanical support. Avoid placing tall electrolytic capacitors or relays directly beside the microcontroller where they can complicate insertion or increase vibration stress. Confirm the manufacturer's minimum board and copper-heat-sink recommendations, particularly if the operating environment approaches the verified +105°C upper temperature limit.
Use short, clean routing for the clock signal and provide the oscillator and load components specified by Zilog. Avoid routing high-current outputs or switching edges alongside sensitive digital inputs. If the controller senses long external wires, add suitable protection, filtering, and return paths; the verified material does not specify internal oscillator accuracy, ADC performance, or input noise immunity.
コンプライアンス情報
The verified JLCPCB and Lisleapex listings identify the Z86E0812PEG as RoHS compliant. The available records do not establish REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. AEC-Q100 is marked not applicable because this industrial 8-bit microcontroller is not presented as an automotive-qualified variant.
