Z86E6116FSG - 16MHz Z8 MCU, 16KB OTP | Zilog
N.º de pieza: Z86E6116FSG ✓ ActivoZ86E6116FSG Descripción general
An 8-bit microcontroller is a programmable integrated circuit that combines a processor core, program memory, data memory, and peripheral interfaces on one chip. The Z86E6116FSG belongs to the Z8 family, where its compact instruction set, dedicated I/O resources, and integrated serial interface support deterministic control of embedded products. Its 16MHz operating speed provides the timing capability needed for protocol handling, input scanning, and actuator control.
The principal feature set includes 16KB of OTP program memory, 236 x 8 bytes of RAM, 32 general-purpose I/O pins, and one UART/USART interface. OTP memory permits a finished program to be written permanently, which can help prevent accidental firmware changes in production equipment. The 32 I/O pins provide substantial host connectivity for switches, indicators, sensors, and control signals without requiring a separate external I/O expander.
Its 5V operating context and 16MHz clock position the device as a compact embedded-control solution. The UART/USART allows a controller to exchange framed serial data with another processor, transceiver, or service interface, while the general-purpose I/O pins handle discrete peripherals. Since program memory is OTP rather than reprogrammable Flash, firmware development and update strategy must account for the permanent nature of the programmed contents.
Typical applications include serial-controlled instrumentation, industrial control modules, keypad and display interfaces, programmable logic controllers, building-control endpoints, and compact communications equipment. The combination of 32 I/O pins, serial connectivity, and 16KB of program storage is useful when the design needs a dedicated controller rather than a high-performance processor.
PCB design should account for all 44 package leads, correct decoupling near the supply pins, and clean routing of the 16MHz clock and serial signals. The 10x10 mm LQFP footprint is relatively compact, but its fine-pitch leads still require careful fanout, solder mask design, and inspection under magnification.
This product page consolidates the device identity, package details, technical constraints, sourcing workflow, and engineering guidance into one reference. It also distinguishes verified drop-in replacements from merely similar microcontrollers, helping designers avoid changes that would require new PCB artwork, firmware revision, or peripheral revalidation.

Aplicaciones típicas
Z86E6116FSG es adecuado para 6 aplicacións: Serial Instrument Controller, Industrial Control Module, Programmable Logic Controller, Building Control Endpoint, Keypad and Display Interface, Compact Communications Equipment.
Serial Instrument Controller
The Z86E6116FSG fits a serial instrument controller because its 16MHz Z8 core can coordinate protocol timing while 32 general-purpose I/O lines operate buttons, indicators, and control signals. Its 16KB of OTP program memory is useful when the instrument firmware is finalized during manufacturing and field updates are unnecessary. The integrated UART/USART connects the controller to a host or communications module. Designers should reserve decoupling and UART routing space in the 44-LQFP layout and validate the firmware against the device's documented peripheral behavior.
Recomendado
Industrial Control Module
The Z86E6116FSG is appropriate for a compact industrial control module that must combine local discrete I/O with a serial supervisory interface. Its 32 general-purpose I/O pins can connect digital sensors, relays, status indicators, and interlock signals, while the 16MHz clock supports deterministic input and output servicing. The 16KB OTP memory supports a fixed control program, but production changes require a new programmed device. Use careful power distribution and signal conditioning to protect the microcontroller from industrial transients and ground potential differences.
Recomendado
Programmable Logic Controller
The Z86E6116FSG can serve as the central controller in a small programmable logic controller because it combines 32 general-purpose I/O pins with 16KB of OTP program memory and a dedicated UART/USART. A fixed ladder-style or event-driven control program can monitor inputs, determine output states, and exchange diagnostic data through the serial port. The 16MHz operating frequency provides processing headroom for communication and control tasks. Firmware design should include startup sequencing, watchdog-style timeout handling, and comprehensive input validation before outputs are enabled.
Recomendado
Building Control Endpoint
The Z86E6116FSG suits a building-control endpoint that must aggregate local sensor and switch inputs while reporting state through a serial network. Its 32 I/O pins reduce the need for multiple low-level interface ICs, and the 16MHz Z8 core can service timers, status logic, and UART traffic. Because program storage is OTP, the device is best suited to fixed configuration and long-life building equipment. Firmware should provide input debouncing, reliable state retention, and controlled output startup to prevent unwanted actuator operation after power restoration.
Recomendado
Keypad and Display Interface
The Z86E6116FSG can manage a keypad, indicators, and a display interface because it combines 32 general-purpose I/O lines with a 16MHz processing core and 16KB of program storage. The microcontroller can debounce user inputs, update status LEDs, and exchange configuration data through the UART/USART. This makes it useful in access panels, laboratory equipment, and compact operator interfaces. The design should account for display-bus timing, input debounce requirements, and the permanent nature of OTP firmware when creating the production programming process.
Recomendado
Compact Communications Equipment
The Z86E6116FSG fits compact communications equipment that needs a dedicated protocol controller alongside discrete control functions. Its UART/USART handles serial framing, while the 32 general-purpose I/O lines monitor link indicators, reset controls, and peripheral enables. The 16KB OTP program memory is practical for a fixed communication protocol and device behavior. Hardware integration should isolate external interfaces, provide regulated supply voltage near the device, and use the manufacturer pin descriptions to assign boot, clock, and reset functions correctly.

Notas de diseño
Assign the 44-LQFP footprint directly from the manufacturer package drawing, including lead pitch, pin-1 orientation, and any exposed thermal-pad geometry. Route the 16MHz clock with short, symmetric connections and keep the UART/USART traces away from high-current switching edges. Place the required bypass capacitors at the power and ground pins using the manufacturer datasheet layout, then maintain a continuous ground reference beneath the device.
Design the 5V supply path to remain within the device's documented operating limits under startup, switching, and I/O loading conditions. Keep series impedance or filtering elements outside sensitive signal paths, and provide local bypass capacitance where the application requires stable rail behavior. Verify brownout and power-up behavior at the system level, especially when the OTP program controls external relays or actuators.
Treat the 16KB program memory as permanently writable once programmed. Build a controlled programming and revision-control process so an incorrect firmware image is detected before it reaches the programmed device. Do not assume Flash-style field updates are available. Likewise, do not substitute a 32-pin Flash MCU solely for similar clock speed; its package and peripheral assignments differ from the 44-LQFP Z86E6116FSG.
Give the UART/USART interface clean return paths and route it away from motors, relays, switching converters, and other high-edge-rate circuits. If the serial line leaves the board, add the appropriate protection or transceiver at the connector rather than relying solely on the MCU pins. Validate logic levels, baud-rate tolerance, and grounding against the final interface specification before production release.
