Z86E3412SSG - 12MHz 16KB OTP 8-Bit MCU | Zilog
部品番号: Z86E3412SSG ✓ 生産中Z86E3412SSG 概要
An 8-bit microcontroller is a microprocessor and embedded-control IC built around an 8-bit processing architecture. The Z8 family belongs to the broader hierarchy of embedded processors, microcontrollers, and semiconductors. One-time programmable memory allows firmware to be written once during manufacturing or programming, providing nonvolatile program storage without the removable-program-memory cost of EEPROM. This makes the Z86E3412SSG suitable for fixed-function products whose firmware does not need field updates.
The principal device characteristics include a 12 MHz operating frequency, 16 KB of OTP program memory, 8-bit processing, CMOS construction, and a 28-pin SOIC package. The reported operating-temperature range for this exact ordering code is 0°C to +70°C. The part is also identified as Pb-free, although separate RoHS, REACH, and halogen-free declarations were not included in the supplied source data and therefore remain unconfirmed.
The 12 MHz clock rate provides the timing headroom expected from a Z8-class embedded controller, while the 16K x 8 OTP organization determines the available program address space. Because the source data does not provide RAM capacity, I/O pin assignments, peripheral inventories, electrical limits, watchdog behavior, or timing characteristics, those details must be confirmed in the manufacturer datasheet before a board design is released.
Typical uses include fixed-function industrial controllers, appliance-control panels, small instrument controllers, status interfaces, and embedded control modules where an 8-bit processor and OTP firmware storage are sufficient. Its 28-pin SOIC package also supports conventional surface-mount assembly, but package dimensions, pin geometry, and exposed thermal requirements are not included in the supplied evidence.
For new layouts, engineers should verify the complete 28-pin pinout, required decoupling, oscillator connection, programming method, reset requirements, and absolute maximum ratings against the official datasheet. The OTP programming process should also be coordinated with manufacturing because an incorrectly programmed device generally cannot be rewritten like flash memory.
This page consolidates the verified distributor listings, an identified same-package family alternative, package constraints, pricing evidence, and engineering-selection guidance. It also clearly separates confirmed Z86E3412SSG facts from electrical and programming details that require manufacturer documentation.

主な用途
Z86E3412SSG の用途: 6 件s: Fixed-Function Appliance Controller, Industrial Status and Sequencer, Small Instrument Control Panel, LED and Indicator Sequencer, Battery-Powered Embedded Module, Programmable Logic Controller.
Fixed-Function Appliance Controller
The Z86E3412SSG fits a fixed-function appliance controller because its 8-bit architecture, 12 MHz operating frequency, and 16 KB of OTP program memory provide sufficient control capability for sequential logic, user-interface coordination, and actuator management. OTP is useful when the finished appliance does not require field-updatable firmware. The controller would typically run from a local supply and use its I/O for switches, indicators, and discrete loads. Before schematic release, confirm the device's exact voltage range, I/O count, timer resources, and pin assignments in the manufacturer datasheet.
おすすめ
Industrial Status and Sequencer
The Z86E3412SSG is suitable for an industrial status-and-sequencing module where a compact 8-bit MCU must coordinate discrete inputs, indicators, relays, and a defined operating sequence. Its 12 MHz clock provides timing capability for digital control tasks, while the 16K x 8 OTP area allows fixed firmware to be stored without external nonvolatile memory. The 28-pin SOIC package supports standard surface-mount assembly. Because galvanic isolation, expanded I/O, and analog inputs were not specified in the supplied records, the controller should be paired with suitable interface circuitry after electrical verification.
おすすめ
Small Instrument Control Panel
The Z86E3412SSG can serve as the control processor in a small instrument panel, coordinating button inputs, status indicators, display commands, and configuration logic. Its 8-bit architecture and 12 MHz operating frequency align with low-complexity panel tasks, while 16 KB of OTP program memory permits the complete fixed control routine to be stored on-chip. The 28-pin SOIC package can simplify assembly compared with a large leaded controller. Engineers should verify pin multiplexing, timing, and peripheral availability because the supplied evidence identifies only the package and principal memory and clock ratings.
おすすめ
LED and Indicator Sequencer
The Z86E3412SSG is appropriate for an LED or indicator sequencer that requires deterministic timing, stored operating patterns, and several digital outputs. A 12 MHz Z8-class controller can execute sequencing logic, while the 16 KB OTP program area avoids an external program-memory device in a fixed product. The MCU can update LEDs through appropriate current-limiting and driver circuits rather than driving loads directly. Exact port count, output-drive characteristics, and maximum GPIO switching conditions are not present in the supplied evidence and must be checked before assigning outputs.
おすすめ
Battery-Powered Embedded Module
The Z86E3412SSG may be evaluated for a small battery-powered embedded module that performs infrequent sensing, state management, and low-duty-cycle control. The device is manufactured using a CMOS process and operates at 12 MHz, but the available source data does not provide active, idle, or shutdown current. Those figures are essential for battery-life calculations. The 16 KB OTP memory can hold fixed application firmware, provided field updates are unnecessary. Verify supply voltage, wake behavior, oscillator options, and current consumption against the manufacturer datasheet before approving the design.
おすすめ
Programmable Logic Controller
The Z86E3412SSG can be considered for a compact programmable logic controller handling discrete inputs, output sequencing, timing, and machine-state logic. Its 8-bit processing architecture and 12 MHz operating frequency are appropriate for deterministic embedded tasks, while the 16 KB OTP program memory provides on-chip firmware storage for fixed configurations. A production PLC design must verify available timers, interrupts, serial interfaces, input thresholds, output-drive capability, and watchdog functions. Those details were not included in the supplied distributor records, so they should be confirmed from the Z86E34-series manufacturer documentation.

設計ノート
Do not treat the Z86E3412SSG as a generic flash-memory MCU without checking its programming workflow. The verified device uses 16 KB of OTP program memory organized as 16K x 8. OTP devices generally cannot be rewritten like flash, so firmware validation, programming fixtures, unique-device serialization, and manufacturing traceability should be completed before programming. Confirm the complete programming interface and electrical timing in the manufacturer datasheet.
Supply-voltage limits, active current, idle current, and shutdown current were not present in the supplied evidence. Do not infer a suitable rail from the 12 MHz clock rating. Select the power supply around the manufacturer's stated operating-voltage range, calculate worst-case dissipation for the actual I/O load, and include bulk plus local ceramic decoupling. Obtain the electrical-characteristics table before finalizing the power tree or battery budget.
The confirmed package is a 28-pin SOIC, but the supplied records do not include pin assignments, package dimensions, or exposed-pad details. Route the confirmed power, ground, clock, reset, and programming signals according to the official datasheet rather than the package name alone. Keep the oscillator and programming-access traces short, provide a clean ground reference, and verify the land pattern against the manufacturer's mechanical drawing before fabrication.
Although the 28-pin SOIC is a surface-mount package, the available data does not confirm how many pins are usable general-purpose I/O or which functions are multiplexed. Perform a complete pin-budget analysis before assigning sensors, indicators, communications, or actuator outputs. This prevents placing two functions on a shared pin and provides time to add an expander or interface IC if the available I/O budget is insufficient.
コンプライアンス情報
The supplied datasheet index identifies Z86E3412SSG as Pb-free. Separate RoHS, REACH, halogen-free, and conflict-minerals declarations were not provided, so those statuses remain unknown. AEC-Q100 is not applicable because this is an industrial/consumer microcontroller rather than an automotive-qualified device.
