Z86E6316VSG - 8-Bit 16MHz 32KB OTP MCU | Zilog
부품 번호: Z86E6316VSG ✓ 활성Z86E6316VSG 개요
A microcontroller is a programmable system-on-chip that integrates a CPU, nonvolatile program memory, data memory, and peripherals into one component. The Z86E6316VSG belongs to the Z8 family of 8-bit microcontrollers, a category used for cost-sensitive embedded control, monitoring, keypad, appliance, and industrial-control designs. Its OTP program memory allows the final firmware to be written once after programming and is not electrically rewriteable.
The principal device characteristics are a 16 MHz operating frequency, 32 KB of OTP program memory, 236 bytes of RAM, a 4.5 V to 5.5 V supply range, and integrated UART capability. The 236-byte RAM figure distinguishes internal data memory from the 32 KB program area and should be considered when sizing buffers, communication queues, and application state. The listed 44-LCC package also provides more external connection options than the small leaded-chip carriers commonly used for basic 8-bit control.
The Z8 architecture is designed around an 8-bit CPU and embedded peripherals rather than a high-level application processor. That architecture is appropriate when firmware must handle timers, serial communication, discrete inputs, and output control within deterministic response requirements. Because program memory is OTP rather than mask-programmed ROM, the device can support application-specific firmware while retaining a single finished component configuration.
Typical uses include serial-connected controllers, industrial modules, instrumentation interfaces, appliance control boards, and embedded system nodes. The UART is particularly useful for connecting the MCU to a host controller, sensor interface, display controller, or service port. For designs needing more general-purpose serial connectivity, the Zilog MCU can work alongside a dedicated interface device such as the MAX232DR or MAX202IDR.
A critical design consideration is that OTP memory cannot be updated after programming. Firmware validation, programming fixtures, and board bring-up procedures should therefore be completed before large-volume deployment. Decoupling, oscillator stability, reset behavior, and exposed-pin assignments must also be checked against the manufacturer datasheet because a PLCC replacement is not automatically a functional replacement.
This page consolidates verified distributor specifications, package and memory details, pricing references, candidate drop-in alternatives, and practical replacement guidance that are not presented together on a single distributor listing. It also distinguishes documented facts from fields that still require confirmation from the Zilog datasheet.

UART-Based Embedded Control Module
The Z86E6316VSG fits a compact serial control module because it combines a 16 MHz Z8 core, 32 KB of OTP program memory, 236 bytes of RAM, and UART capability in one 44-LCC device. The UART can connect the controller to a host computer, configuration tool, sensor interface, or downstream actuator node, while the OTP area stores the final application firmware. One practical implementation places the MCU beside a MAX232DR or MAX202IDR when the field bus uses RS-232. Designers should treat the 236-byte RAM as the limiting factor for buffering and reserve the program area for complete firmware before programming.
추천
Industrial Instrumentation Interface
The Z86E6316VSG is appropriate for a small instrumentation interface that must translate sensor status and control commands over a UART. Its 8-bit architecture is sufficient for supervisory tasks, while the 16 MHz operating frequency provides practical headroom for interrupt handling and protocol processing. The 4.5 V to 5.5 V supply range permits operation from a regulated 5 V rail, subject to the transient limits in the manufacturer datasheet. In a measurement system, a PCA9536DR can expand digital control or status lines and an ATMEGA328P-MNR can serve as an adjacent acquisition controller when duties exceed the Z86E6316VSG's memory budget.
추천
Appliance and Household Controller
The Z86E6316VSG suits a dedicated appliance controller in which a fixed program handles relays, buttons, indicators, and a service UART. Its 32 KB OTP memory accommodates a deterministic embedded program, while 236 bytes of RAM can support task variables and small serial buffers. Because OTP cannot be re-programmed, the manufacturing process should include a firmware checksum, a verified programming fixture, and a board test that confirms output states before the device is programmed. A TCA4311DR may provide voltage supervision, and a PCA9536DR can add configurable digital I/O when the 44 available package leads are not sufficient.
추천
Serial Service Port and Configuration Interface
The Z86E6316VSG can serve as the controller for a service port that exposes configuration commands, diagnostics, or a simple maintenance interface. Its integrated UART avoids allocating a separate serial transceiver protocol engine inside the MCU, and the 16 MHz clock provides useful margin for command parsing and checksum handling. The interface should expose only documented commands and avoid remote memory-write functions unless the design includes authentication and validation. A MAX202IDR is suitable where the service connection is RS-232, while the device's OTP program memory ensures that the released configuration logic remains fixed after programming.
추천
LED and Illumination Control Board
The Z86E6316VSG can control a bank of LEDs or illumination channels where the board needs deterministic timing, serial adjustment, and a compact control hierarchy. Timed sequences and dimming commands can be managed from the 32 KB OTP program, while a PCA9536DR expands the number of controlled outputs without loading every lamp signal directly through the MCU. The verified 236-byte RAM must be checked against animation tables, communication buffers, and any debounce state. For larger lighting systems, a TAS5711PHP audio amplifier is not a direct substitute, but a dedicated LED-driver IC from the Power Management category would be a better companion than an audio device.
추천
Dedicated Protocol and Data-Gateway Front End
The Z86E6316VSG is useful as a protocol front end when a larger processor needs a small, deterministic helper for framing, routing, or configuration traffic. The UART and 16 MHz operating speed support common serial tasks, while the OTP program memory permits product-specific protocol conversion to be retained in one device. An ATMEGA1281-16AUR or ATMEGA128A-MU can act as the higher-level host, with the Z86E6316VSG handling a dedicated endpoint. This division of labor works only after confirming that the Z8 firmware's 236-byte RAM is adequate for buffering; larger frame queues should move to the companion processor.

설계 노트
Do not treat the 32 KB program memory as flash. The Z86E6316VSG uses one-time-programmable memory, so a programming error cannot be corrected by rewriting the MCU. Validate the complete image, boot sequence, interrupt vectors, checksums, and peripheral configuration in a development system before programming production units. A fixture that automatically verifies the OTP contents can prevent shipping boards with an unrecoverable program.
Design the board for a 4.5 V to 5.5 V supply range. Place the manufacturer's recommended bypass capacitors close to the supply pins and route them to provide a low-impedance return path. Because the verified snippets do not include maximum supply ripple, input-voltage transients, or per-pin current limits, those values must be obtained from the Zilog datasheet rather than inferred from the nominal 5 V operating point.
The 44-LCC J-lead package is a through-hole footprint and differs materially from common surface-mount MCU land patterns. A cross-family or cross-package substitute cannot be fitted by rearranging a few leads; track, drill, pad, and courtyard geometry must be compared. Even a nominal 44-LCC alternative requires a pin-by-pin review because programming, reset, oscillator, UART, and interrupt assignments may be arranged differently.
Keep the clock source, reset network, and UART signal routing short and away from switching nodes and high-current loads. The captured data confirms 16 MHz operation but does not specify whether the design requires an external crystal, ceramic resonator, or oscillator. Select that circuit only after reviewing the Zilog clocking section, then provide a defined ground reference and keep programming or test access reachable for production inspection.
규정 준수 정보
LCSC lists the Z86E6316VSG as RoHS compliant. No supporting REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations were present in the verified web data, so those fields remain unknown.
