Z86E3016SSG - 8-Bit 16MHz OTP Microcontroller | Zilog
部品番号: Z86E3016SSG ✓ 生産中Z86E3016SSG 概要
A microcontroller is an integrated circuit that combines a processor core, nonvolatile program memory, working RAM, and peripherals on one semiconductor device. The Z86E3016SSG belongs to the Z8 family of 8-bit microcontrollers and provides a compact control platform for products that require deterministic digital control but do not need the processing power, memory, or peripheral complexity of a 32-bit embedded processor. Its one-time-programmable architecture is intended for production devices whose firmware does not need field reprogramming.
The principal device characteristics include a 16 MHz clock, 4 KB OTP program memory organized as 4K by 8 bits, 125 bytes of RAM, and 24 general-purpose I/O lines. Integrated power-on reset and watchdog-timer functions support dependable startup and recovery behavior. The 28-pin surface-mount SOIC package supports conventional PCB assembly while providing enough I/O capacity for sensors, indicators, control inputs, and external logic.
The Z8 processor architecture provides an 8-bit execution model optimized for control-oriented embedded systems. At 16 MHz, it offers substantially greater timing headroom than many simpler 8-bit controllers, while the compact instruction and memory architecture keeps firmware and peripheral integration straightforward. Programmable OTP options include an RC oscillator and EPROM protection, allowing the selected configuration to be fixed according to the product's operating requirements.
Typical uses include appliance controllers, industrial control modules, security and access-control equipment, instrumentation peripherals, and small embedded control subsystems. In each case, the 24 available I/O lines and 125 bytes of RAM are important constraints. Designers should allocate RAM carefully for stacks, buffers, and intermediate state, while treating the 4 KB OTP capacity as the final firmware limit.
The primary design consideration is that one-time-programmable memory cannot be changed after programming. Firmware validation, programming fixtures, and production traceability therefore must be completed before devices reach end users. PCB layouts should also follow the verified 28-SOIC footprint and provide the decoupling and clock circuitry required by the manufacturer datasheet.

主な用途
Z86E3016SSG の用途: 6 件s: Appliance Control Module, Industrial Control Interface, Security and Access-Control, Instrumentation Front Panel, Battery-Powered Sensor Node, Compact Embedded Subsystem.
Appliance Control Module
The Z86E3016SSG fits appliance-control boards that coordinate buttons, indicators, relays, and simple sensors within a fixed 4 KB firmware budget. Its 16 MHz Z8 core provides timing headroom, while 24 I/O lines can connect multiple control points without requiring a larger external interface. The 125-byte RAM supports modest state variables and short working buffers, although it requires disciplined allocation for stack depth, debounce state, and communications. Because the program memory is one-time programmable, the controller is best suited to products whose firmware is finalized and validated before production. The 28-SOIC package is straightforward for conventional surface-mount assembly, provided the layout follows the manufacturer footprint and decoupling guidance.
おすすめ
Industrial Control Interface
Z86E3016SSG can serve as the local controller for an industrial interface that reads switches and sensors and drives discrete outputs. Its 4.5 V to 5.5 V operating range supports conventional 5 V control logic, and the 24 available I/O lines are valuable when a system needs multiple inputs and outputs. The specified 0°C to 70°C ambient range is appropriate for many indoor industrial environments, though it should not be treated as an extended-temperature rating. The integrated power-on reset and watchdog timer help improve startup and recovery behavior. Firmware engineers must ensure the 4 KB OTP limit accommodates control logic, and production programmers should verify programming voltage, timing, and device identifiers before deployment.
おすすめ
Security and Access-Control
The Z86E3016SSG is applicable to compact access-control peripherals that manage keypad inputs, lock or relay commands, status LEDs, and communication interfaces. Its 24 I/O lines provide sufficient parallel connectivity for common peripheral combinations, while the 16 MHz clock supports responsive input scanning and control sequencing. The one-time-programmable architecture can protect finalized control firmware from casual modification after manufacturing. However, product designers should determine whether OTP is appropriate for security-critical code because it changes update and recovery procedures. The 125-byte RAM is adequate for modest protocol and state handling but may constrain sophisticated cryptographic buffering. Pin-level security functions and programming protection requirements must be verified from the manufacturer documentation.
おすすめ
Instrumentation Front Panel
A measurement instrument or test fixture can use Z86E3016SSG to control front-panel indicators, buttons, mode selection, and relay-based switching. The device's 16 MHz processing rate is useful for deterministic panel tasks, and the 4 KB OTP program store can hold a compact control application without requiring external program memory. With 125 bytes of RAM, the design should minimize simultaneous buffers and favor event-driven processing over large data histories. The 28-SOIC footprint supports conventional PCB assembly, but every analog or sensor signal still requires separate conditioning and protection. Before layout release, engineers should verify oscillator requirements, programming contacts, bypass placement, and all 28 pin assignments using the official datasheet.
おすすめ
Battery-Powered Sensor Node
Z86E3016SSG can control a low-duty-cycle sensor node when the design is optimized for its 16 MHz clock and 4.5 V to 5.5 V supply range. Power consumption is not specified in the supplied data, so battery life must be estimated from actual datasheet operating currents rather than assumed. The 24 I/O lines support sensors, indicators, and external switching, while 125 bytes of RAM limits how much sensor data can be buffered at one time. The one-time-programmable architecture suits sealed, low-maintenance products, but field updates will require replacement hardware. Board-level design should minimize continuously active peripherals, validate startup behavior, and confirm that the chosen regulator or battery source remains within the documented voltage range.
おすすめ
Compact Embedded Subsystem
Z86E3016SSG is appropriate for compact embedded subsystems that need local logic, modest storage, and multiple digital I/O rather than a high-performance application processor. Its 8-bit Z8 core, 16 MHz clock, and 24 I/O lines can handle sequencing, state machines, and peripheral coordination in a single device. The 4 KB OTP memory places a firm ceiling on code size, so modular coding and unused-feature elimination are important. The integrated watchdog can recover a stuck control sequence, although its exact timeout behavior must be checked in the manufacturer documentation. A designer should also account for the limited 125-byte RAM and avoid architecture that depends on large buffers. The 28-SOIC package supports straightforward manufacturing without requiring a fine-pitch land pattern.

設計ノート
Treat OTP programming as a production gate rather than a routine firmware-update step. The verified device has only 4 KB of OTP program memory, and the supplied records do not state the programming voltage, timing, or supported programmer models. Validate the complete image, boot behavior, watchdog settings, and I/O assignments before programming devices. If later firmware correction is required, a flash-memory MCU may be more practical than an OTP-only replacement.
Route the 28-SOIC footprint only from the verified manufacturer pinout and land pattern; the supplied search results identify the package but do not enumerate individual signals. Keep programming contacts and power paths accessible if the design includes a socket or pogo-pin fixture. Place the required bypass capacitor close to the device supply pins and keep oscillator or RC-oscillator components close to their associated pins. Verify all 28 locations against the package drawing before fabrication.
Design the supply for the verified 4.5 V to 5.5 V operating range and account for startup and load-transient behavior at the board level. The supplied sources do not provide average or sleep-mode current, so battery and power-consumption calculations cannot be completed from the available data. Use the manufacturer datasheet for operating-current and power-consumption limits. Avoid relying on a 5 V rail without checking its tolerance under the worst-case load and temperature.
Plan the 125-byte RAM budget before finalizing firmware architecture. It must accommodate the stack, interrupt state, communication buffers, and application variables, leaving little space for large data arrays. Prefer event-driven processing and compact state representations. The 24 I/O lines are also a finite resource and should be assigned early, with any multiplexed peripheral functions checked against the authoritative pin table.
コンプライアンス情報
The supplied sources do not contain RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 declarations. AEC-Q100 is marked not_applicable because no automotive qualification was claimed, but this is not evidence of automotive approval.
