Z86E6316ASG - 8-Bit 16MHz 32KB MCU | Zilog
Référence : Z86E6316ASG ✓ ActifZ86E6316ASG Présentation
An 8-bit microcontroller is a compact embedded-control IC that executes instructions using an 8-bit data path. Within the semiconductor hierarchy, a microcontroller belongs to the embedded processor family and integrates a CPU core, program memory, data memory, peripherals, and I/O on one die. The Z8 family provides the base architecture for the Z86E6316ASG, while OTP memory allows firmware to be programmed once for stable production operation without external program-memory components.
The principal identified specifications include an 8-bit processor, a 16 MHz operating frequency, 32 KB organized as 32K by 8 bytes of OTP memory, and a 5 V operating condition. The integrated UART supports serial communication with sensors, human-interface equipment, data converters, and other embedded controllers. Its 44-LQFP package provides 44 external lead positions and a 10 mm by 10 mm footprint suitable for compact embedded-control boards.
The Z86E6316ASG belongs to the Zilog Z86 device family and uses the Z8 CISC architecture. Its one-time-programmable memory is intended for permanent application firmware, reducing the board-level component count compared with a system that uses an external programmed memory device. Because this is an OTP device, firmware changes after programming require a different device rather than an in-circuit rewrite, which should be considered before committing the design to production.
Typical applications include industrial serial controllers, instrument interfaces, appliance-control modules, keypad and display controllers, and compact embedded automation nodes. The 16 MHz clock and UART are particularly useful for supervisory tasks such as collecting switch or sensor states, formatting serial data, and controlling peripheral functions. The 44-LQFP package also offers more I/O than smaller low-pin-count microcontroller packages while retaining a conventional leaded surface-mount footprint.
Hardware design should follow the pin-description and recommended decoupling information in the Zilog manufacturer datasheet. Place the supply bypass capacitor close to the device, route oscillator and reset signals away from high-current switching nodes, and confirm the program voltage and OTP programming procedure before manufacturing. Designers should also verify that all 44 package leads are assigned because the complete public pin table is not included in this page's structured dataset.
This product page consolidates the verified device identity, package information, lifecycle status, source listings, application guidance, and a qualified replacement candidate into one engineering reference. It also highlights the distinctions that matter when evaluating an OTP MCU replacement, particularly firmware programmability, package compatibility, UART availability, clock rate, and memory capacity.

Applications typiques
Z86E6316ASG convient pour 6 applications: Industrial Serial Controller, Appliance Control Module, Sensor Data Concentrator, Instrument and Meter Interface, Keypad and Display Controller, Embedded Automation Node.
Industrial Serial Controller
The Z86E6316ASG fits an industrial serial controller because its 16 MHz Z8 CISC core can manage protocol handling and supervisory logic while the UART provides a dedicated serial interface. The 32 KB OTP memory supports permanent operating firmware for production equipment. Place the device between the system bus and an RS-232, RS-422, or other differential transceiver, and match logic levels to the selected interface. Its 44-LQFP package exposes substantially more I/O than a small 8-pin controller, allowing status LEDs, interlocks, and local inputs to share the same device.
Recommandé
Appliance Control Module
The Z86E6316ASG can serve as the central controller in an appliance module because its 32 KB OTP store is sufficient for fixed control sequences, sensor-state logic, and diagnostics. The 16 MHz operating frequency provides headroom for multitasking communication and control updates, while the UART connects to a display board, keypad controller, or service interface. Because program memory is one-time programmable, firmware should be validated before final programming. Use the 44-LQFP package to implement separate controls, indicators, and safety interlocks without introducing another microcontroller.
Recommandé
Sensor Data Concentrator
The Z86E6316ASG is suitable for a small sensor data concentrator when the system must aggregate digital sensor inputs and forward them through a serial link. Its 8-bit Z8 CISC core supports the control and packet-formatting tasks expected from an embedded UART controller, and the 16 MHz clock allows communication work to coexist with periodic input sampling. The 32 KB OTP region can store a fixed protocol stack and device map. Confirm analog sensor conditioning separately, and use the UART only where the selected sensor or transceiver supports the corresponding logic levels.
Recommandé
Instrument and Meter Interface
The Z86E6316ASG can control a compact instrument front end where digital measurements, keypad events, and status indicators need coordinated handling. Its 16 MHz processing rate supports responsive menu and communication tasks, while UART provides a path to a host computer or configuration fixture. The 32 KB OTP memory is appropriate for a fixed measurement-control application that does not require field firmware updates. Follow the manufacturer datasheet for oscillator stability, reset behavior, and supply bypassing when accurate timing or reliable communications are important.
Recommandé
Keypad and Display Controller
The Z86E6316ASG works well as a keypad, display, and communication controller because it combines a 16 MHz 8-bit processor with 32 KB of permanent firmware and a UART interface. The controller can scan inputs, update display commands, and report user activity through the serial port. Its 44-LQFP package provides a useful balance between I/O access and compact board area. Define the scan rate and display-refresh timing in firmware, and check timing requirements in the manufacturer datasheet before relying on a particular polling interval.
Recommandé
Embedded Automation Node
The Z86E6316ASG can act as a low-cost automation node for local digital I/O, mode control, and supervisory serial communication. Its 8-bit Z8 architecture is suited to deterministic control tasks, and the 16 MHz clock provides ample execution headroom for UART protocol handling. The 32 KB OTP memory supports a fixed control program rather than remotely updated firmware. Use the 44-LQFP leads for field inputs and outputs, add appropriate signal conditioning for external sensors, and apply the manufacturer's recommended power and layout practices for reliable industrial operation.

Notes de conception
Use the Zilog manufacturer datasheet pin-description table to assign every one of the 44 LQFP leads before routing the board. Place the supply bypass components at the device power pins, with short, direct ground returns, and keep sensitive oscillator or programming nets away from switching nodes. Because the package is 10 mm by 10 mm, adequate solder-mask and paste control are important for reliable lead formation on production assemblies.
Confirm the allowed supply tolerance, operating current, and peripheral-load limits in the manufacturer datasheet before finalizing the 5 V power network. Provide local high-frequency bypass at the controller and decouple any UART transceiver or other switched load separately to prevent supply transients from disturbing the MCU rail. Verify brownout and reset behavior across the full power sequence, especially when the UART remains connected to powered external equipment.
Do not assume that an A-to-F order-code suffix is electrically insignificant. Validate Z86E6316FSG against Z86E6316ASG for pin function, clock tolerance, UART behavior, OTP organization, temperature range, qualification status, and programming procedure. The OTP architecture also means production firmware cannot normally be corrected in place, so test the complete image and programming sequence on representative hardware before releasing a build.
Follow the manufacturer layout guidance for the oscillator network, reset circuit, programming interface, and decoupling. Keep the oscillator loop compact and symmetric, isolate it from UART and switching-node routing, and reserve accessible test pads if production programming or diagnostics are required. The 44-LQFP footprint offers enough pins for dedicated programming and serial functions, so avoid combining unrelated high-current signals with sensitive control traces.
