Z86E0308SSG - 8-Bit 8MHz OTP Microcontroller | Zilog
部品番号: Z86E0308SSG ✓ 生産中Z86E0308SSG 概要
An 8-bit microcontroller is a compact computing device designed to execute control logic, monitor inputs, and drive outputs within appliances, instruments, and industrial equipment. The Z86E0308SSG belongs to the Z8 microcontroller family, combining a processor core, OTP program memory, timers, and serial I/O in one package. This architecture suits sequential control tasks where deterministic behavior and low component count matter more than high-bandwidth processing.
Principal characteristics include an 8 MHz clock, 512 bytes of OTP program memory, and operation across a 3 V to 5.5 V supply range. Its 18-pin SOIC-18-300mil package supports conventional PCB assembly and inspection. The industrial temperature classification, gull-wing terminal arrangement, and rectangular package geometry are useful constraints when laying out a new board or sourcing a mechanically similar replacement.
The Z8 architecture is intended for embedded control rather than high-volume data processing. One-time-programmable memory makes the programmed version of the device suitable for products whose firmware does not require field updates. Because the memory cannot be rewritten after programming, production programming, blank-device handling, and firmware revision control must be planned before devices reach the assembly line.
Typical uses include small appliance controllers, instrumentation front ends, industrial control modules, sensor interfaces, and dedicated timing or sequence-control products. In these applications, the MCU can evaluate digital inputs, operate timers, update displays, and communicate with external peripherals while keeping the external component count and board area modest.
When designing a board, verify the exact pin assignments, port capabilities, oscillator requirements, and programming interface against the manufacturer datasheet before routing signals. The 300 mil SOIC body is wider than a narrow 150 mil SOIC, so component clearance, connector placement, and assembly tooling must accommodate the specified package rather than a generic 18-pin footprint.
This page consolidates distributor specifications, package constraints, drop-in comparison information, and application-level engineering guidance. It also distinguishes documented parameters from values that must be confirmed with Zilog before schematic release, helping designers move from part selection to a controlled PCB and firmware implementation.

主な用途
Z86E0308SSG の用途: 6 件s: Small Appliance Control, Industrial Sensor Interface, Instrumentation Front Panel, Dedicated Sequence and Timer Control, Programmable Relay and Driver Module, Battery-Powered Measurement Node.
Small Appliance Control
The Z86E0308SSG fits compact appliance controllers that sequence motors, heaters, indicators, and user inputs. Its 8 MHz operating rate provides sufficient timing resolution for debouncing, delayed events, and state-machine control, while the 3 V to 5.5 V range supports common low-voltage rails. The 512-byte OTP memory suits products whose firmware becomes fixed at the end-of-line programming stage. Because OTP cannot be updated in the field, any firmware correction requires a newly programmed device, so production change control is essential.
おすすめ
Industrial Sensor Interface
The Z86E0308SSG can supervise discrete sensors, threshold inputs, and status lines in a compact industrial interface module. Operating from 3 V to 5.5 V permits integration with 3.3 V sensor networks or 5 V control boards, and the 8-bit Z8 core is suitable for sampling states and implementing deterministic control logic. Its 512 bytes of OTP memory limits firmware size, so the application should use compact tables and avoid unnecessary diagnostic code. Industrial-temperature classification should be confirmed for the exact operating environment.
おすすめ
Instrumentation Front Panel
For a keypad-driven test instrument, the Z86E0308SSG can scan controls, update status indicators, and manage a simple measurement sequence. The 18-pin SOIC-18-300mil package leaves board area for external analog and interface circuitry, while the 8 MHz clock supports responsive event handling. The 512-byte OTP region is adequate only for compact menu and sequencing logic; larger buffers or protocol stacks may require a higher-memory microcontroller. Use the pin table to allocate port lines for the display, keys, and serial communications.
おすすめ
Dedicated Sequence and Timer Control
The Z86E0308SSG is appropriate for products that execute a fixed sequence of timed events, such as dispensers, test fixtures, or simple actuator controllers. At 8 MHz, the MCU can divide an internal time base, debounce start commands, and operate multiple outputs according to a compact state machine. The OTP program memory suits a finalized sequence that never changes after production programming. Designers should reserve pins for the time-base source and output drivers, and verify whether the required timer resources fit the device's peripheral set.
おすすめ
Programmable Relay and Driver Module
The Z86E0308SSG can serve as the logic controller on a compact relay or driver module, translating commands into timed output activity. Its 3 V to 5.5 V supply range simplifies interfacing with 5 V logic, and the 18-pin package provides a practical footprint for external drivers. The controller should not drive relay coils or other inductive loads directly unless the datasheet explicitly permits the required current. Use transistors, flyback protection, and appropriately rated driver interfaces for inductive outputs.
おすすめ
Battery-Powered Measurement Node
The Z86E0308SSG can coordinate low-duty-cycle measurement tasks in a compact battery-operated node. Its 3.3 V-compatible operating range allows use with low-energy sensors, while the 8-bit processor executes sampling routines and reports results through a simple serial interface. The 512-byte OTP footprint keeps the firmware compact, and one-time programming prevents accidental field changes. Supply current, sleep behavior, and wake-up sources must be checked in the manufacturer documentation before estimating battery life.

設計ノート
Use the manufacturer drawing for the SOIC-18-300mil footprint instead of a generic narrow-SOIC library symbol. The 300 mil body width changes pad length, row spacing, solder-mask geometry, and courtyard requirements. Verify pin-one orientation, paste-land dimensions, and the clearance needed around adjacent components before releasing the PCB artwork.
Design the supply network for the documented 3 V to 5.5 V operating range and place the required bypass capacitance close to the device power pins. Because the Z86E0308SSG is an OTP device, production programming is part of the manufacturing flow; confirm whether programming requires the operating supply to remain within a narrower programming condition before defining the board's power sequence.
Do not treat OTP memory as rewriteable flash. Firmware errors cannot be corrected by erasing and reprogramming the installed MCU, so establish a controlled programming process, retain known-good firmware versions, and verify blank-device handling. Also avoid designing the board around an inferred 18-pin pinout; assign every signal from the official pin-description table.
