MC9S08GT8ACFCE - 40MHz 8KB Flash 8-bit MCU | NXP
MPN: MC9S08GT8ACFCE ✓ Hoạt độngMC9S08GT8ACFCE Tóm tắt
An 8-bit microcontroller is a compact embedded-control device that combines a processor core, programmable Flash memory, digital I/O, interrupts, timers, and communication peripherals on one semiconductor package. Within the hierarchy of embedded processors, this device belongs to the 8-bit microcontroller class and the NXP S08 general-purpose product family. It is appropriate for cost-sensitive control systems where 8 KB of code storage and a 40 MHz clock are sufficient.
Key verified features include an 8-bit CPU architecture, 40 MHz maximum clock, 8 KB Flash memory, 34 I/O ports, operation from 1.8 V to 3.6 V, and support for as many as 32 interrupt and reset sources. The source data also identifies software-selectable pullups on ports when those ports are used as inputs, reducing the need for some external input-conditioning components. The no-lead, 32-terminal package supports compact surface-mount assemblies.
The S08GT architecture combines an enhanced S08 core with general-purpose resources rather than a highly specialized application processor. Its HCS08-compatible instruction set supports compact embedded control code, while the 40 MHz operating speed provides processing headroom for digital state machines, timing, and interface handling. Exact RAM capacity, timer organization, analog peripherals, pin names, and electrical timing limits must be confirmed in the official manufacturer documentation before schematic or firmware release.
Typical uses include industrial control modules, appliance controllers, building-control endpoints, small motor-control logic, keypad interfaces, and sensor-conditioning systems. A 5 mm by 5 mm package is useful where board area is constrained, although exposed-pad thermal and assembly requirements still depend on the exact ordering code and package drawing. Firmware development should use the memory map, interrupt vectors, and pin definitions published for this exact suffix.
When designing a board, begin with the official 32-terminal package drawing and preserve the required decoupling and exposed-pad land pattern. Confirm pin multiplexing before assigning functions because general-purpose ports may support selectable pullups and multiple peripheral roles. Programmers should also verify the supported clock, reset, programming, and operating-temperature details rather than extrapolating them from another S08GT member.
This page combines the verified manufacturer and distributor facts with sourcing, lifecycle, compatibility, and design guidance. It also distinguishes verified characteristics from details that remain unavailable in the supplied search evidence, helping engineers make a responsible preliminary selection before downloading the complete NXP datasheet.

Ứng dụng tiêu biểu
MC9S08GT8ACFCE phù hợp cho 6 Áp dụngs: Compact Industrial Control Module, Appliance Controller, Building-Control Endpoint, Small Motor Sequencing Control, Keypad and Human-Interface Controller, Digital Sensor Aggregator.
Compact Industrial Control Module
The MC9S08GT8ACFCE fits compact control tasks because its enhanced S08 core operates up to 40 MHz while the device provides 8 KB of Flash for firmware and 34 I/O ports for external control signals. The 1.8 V to 3.6 V operating range permits integration with compatible low-voltage sensors, logic, and actuators. Place the MCU in a 32-terminal HVQCCN footprint, preserve its exact exposed-pad land pattern, and verify the package drawing before release. Its principal benefit is compact control without a high pin count; the main limitation is that 8 KB of Flash may constrain larger application programs.

Appliance Controller
The 40 MHz S08GT core and 34 I/O ports make the MC9S08GT8ACFCE relevant to appliance control boards that coordinate buttons, indicators, relays, and simple sensors. Its verified 8 KB Flash capacity is useful for compact fixed-function firmware, while software-selectable pullups can reduce discrete input-conditioning hardware on supported ports. The 1.8 V to 3.6 V supply supports low-voltage logic integration. Engineers should reserve flash space for boot, safety checks, state management, and field updates, and must confirm relay-driver isolation, reset behavior, and exact peripheral assignments.
Được đề xuất
Building-Control Endpoint
The MC9S08GT8ACFCE can support a small building-control endpoint that reads discrete inputs and drives digital outputs through a qualified interface stage. Its 40 MHz processing rate provides headroom for communication state machines, debouncing, diagnostics, and scheduling, while 34 I/O ports expand the endpoint’s discrete connectivity. Software-selectable input pullups may simplify contacts and logic inputs when their electrical limits are suitable. The design must add appropriate isolation, surge protection, and environmental filtering; an MCU package alone does not establish building-automation compliance.
Được đề xuất
Small Motor Sequencing Control
The MC9S08GT8ACFCE is suitable for supervisory sequencing around a small motor system when the MCU handles commands, interlocks, timing, and status rather than directly driving high-current motor windings. Its 40 MHz S08 core can execute rapid state-machine updates, and support for up to 32 interrupt and reset sources provides a foundation for responsive control. The 5 mm by 5 mm, 32-terminal package supports compact assemblies. External MOSFETs, gate drivers, current sensing, and protection are still required; verify every peripheral pin, timer feature, and thermal limit before choosing this device.
Được đề xuất
Keypad and Human-Interface Controller
The 34 available I/O ports give the MC9S08GT8ACFCE useful connectivity for matrix keypads, switches, indicator LEDs, and display-control signals in a compact human-interface module. Its 40 MHz core allows responsive scanning and debouncing, while the 8 KB Flash budget favors fixed interface functions rather than graphics-intensive firmware. Software-selectable pullups can assist eligible digital-input conditioning after the exact pin capabilities are confirmed. Keep high-current LED and display drive away from the MCU pins, provide adequate current limiting, and account for ground bounce in the layout.
Được đề xuất
Digital Sensor Aggregator
The MC9S08GT8ACFCE can aggregate discrete outputs from sensors when the system uses digital interfaces rather than intensive analog conversion. Its 34 I/O ports support multiple digital sources, 40 MHz operation supports protocol and filtering tasks, and the 1.8 V to 3.6 V range aligns with many compact embedded systems. The software-selectable pullup feature may simplify suitable sensor and switch inputs. Designers must still verify analog thresholds, open-drain behavior, ESD exposure, and peripheral multiplexing. Use the official datasheet to determine whether the application also requires ADC resources beyond the verified data.

Ghi chú thiết kế
Use the ordering-code-specific NXP package drawing to reproduce the 32-terminal HVQCCN land pattern, exposed pad, mask-defined versus non-mask-defined geometry, solder-mask clearance, and paste recommendations. The verified body size is 5 mm by 5 mm, but body size alone does not define a manufacturable footprint. Preserve pin 1 orientation and verify the terminal pitch before ordering boards, and use the manufacturer stencil and reflow guidance because thermal-pad solder volume affects voiding and reliability.
Design the 1.8 V to 3.6 V supply path around verified operating limits and the exact pin connections in the official datasheet. Place the required bypass capacitors at their designated power pins, keep the return path compact, and avoid routing noisy switching-current paths beneath sensitive control or communication nets. Because the supplied evidence does not identify internal block functions or detailed current consumption, do not choose capacitor values or regulator capacity from memory; obtain the missing electrical limits from NXP before finalizing the power tree.
Assign every pin from the exact MC9S08GT8ACFCE pin table rather than from a generic S08GT diagram. Separate clock, programming, reset, and communication routes from high-current switching nodes, maintain short ground returns, and place input filtering close to the connector or sensor that creates the noise. Software-selectable pullups can reduce external resistors on supported inputs, but they do not replace bus termination, level translation, isolation, or protection. Validate alternate-function conflicts after assigning all pins in firmware.
Do not assume that any other 8 KB S08GT microcontroller is pin-compatible merely because its memory and clock appear similar. Check package terminal count, pin names, multiplexed functions, reset sources, programming interface, clock architecture, RAM, timer mapping, and electrical limits. The cross-reference evidence supplied for this part contains no verified named drop-in substitute. Treat generic search results as leads, not approvals, and validate any migration with the manufacturer documentation and hardware tests.
