The device integrates an 8-channel 10-bit ADC, SCI/SPI/I2C communication peripherals, and software-selectable port pull-ups, making it suitable for automotive and industrial embedded applications. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals. Within the broader taxonomy, the S08 family is a CISC 8-bit architecture positioned under the Freescale/NXP HCS08 lineage of low-cost, high-performance general-purpose microcontrollers, sitting alongside 16-bit S12 and 32-bit Kinetis families in NXP's automotive-grade portfolio. The GT sub-family emphasizes integration of Flash, RAM, ADC, and serial communication channels at low cost for body and chassis electronics. Key features include 60 KB (60K x 8) Flash program memory, 4 KB SRAM, a 40 MHz maximum CPU frequency, an 8-channel 10-bit ADC, multiple communication interfaces (one SCI, one SPI, one I2C), and a -40 C to +85 C industrial operating range. The 44-QFP package offers a manageable footprint with 34 user I/O lines, ample for keypad scanning, LED drive, sensor aggregation, and discrete control loops. Supply voltage spans 1.8 V to 3.6 V, with low-power wait and stop modes for battery-friendly designs. The HCS08 core uses a 16-bit stack-pointer-indexed instruction set with a BGND (background debug) instruction for non-intrusive in-circuit debugging. Up to 32 interrupt sources support real-time response, and the integrated COP watchdog, LVI (low-voltage detect), and clock monitoring provide robust fault recovery. The internal clock generator with FLL supports an external crystal or resonator across common communication baud-rate frequencies. Typical applications include HVAC control panels, appliance user interfaces, automotive body controllers, security and alarm keypads, and small industrial sensor hubs. The 40 MHz CPU and 60 KB Flash comfortably fit state-machine control plus small RTOS kernels for sensor fusion. The 8-channel ADC supports multi-zone temperature or pressure monitoring, and the SCI/SPI/I2C trio connects easily to motor pre-drivers, EEPROM, or external displays. When designing with this part, budget Flash for a small bootloader if field-upgrade is required, and reserve a hardware timer for software timing precision. Place a 100 nF decoupling cap close to each VDD pin and follow NXP's four-layer or two-layer reference layout recommendations in the datasheet for EMI compliance. The 44-QFP package allows hand-rework and optical inspection on prototype boards. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design guidance that complements the manufacturer datasheet, helping engineers compare MC9S08GT60ACFBE to MC9S08GT32, MC9S08PT16, and MC9S08PA16 variants in the same S08 footprint.

MC9S08GT60ACFDE - 8-Bit 40MHz MCU, 60KB Flash | NXP

The NXP Semiconductors MC9S08GT60ACFDE is an 8-bit S08 general-purpose microcontroller with a 40 MHz processor, 60 KB of Flash memory, 4 KB of RAM, and a 48-pin QFN package with an exposed pad. It operates from 2.5 V to 3.3 V and is identified by NXP as NRND. A microcontroller is a compact embedded-computing device that integrates a CPU, nonvolatile program memory, volatile data memory, peripherals, and input/output interfaces on one semiconductor die. The S08 core uses a CISC instruction set and belongs to the HCS08 family of general-purpose 8-bit controllers. The MC9S08GT family targets cost-sensitive control systems requiring more processing and memory capacity than the smallest 8-bit devices. The verified device data identifies 60 KB of Flash program memory, 4 KB of RAM, an 8-bit architecture, and operation up to 40 MHz. A secondary distributor listing describes the package as a 7 x 7 mm 48-QFN with exposed pad, while the suffix indicates tray packaging. Flash memory supports in-system programming and allows firmware updates without replacing the MCU, while RAM supports working variables, stack operations, and peripheral data handling. The S08 platform integrates communication, timing, analog, and control peripherals, but the verified excerpt does not enumerate their channel counts or block configurations. Detailed peripheral requirements, pin functions, clock options, electrical limits, and thermal ratings should therefore be checked against the manufacturer data sheet before schematic capture or firmware development. Typical uses for this controller class include industrial monitoring, building and appliance controls, motor-control assistance, general embedded products, and compact consumer devices where an 8-bit architecture, 60 KB of program storage, and a QFN footprint are appropriate. Its exposed-pad package also requires deliberate PCB thermal-pad layout and manufacturing planning. The most important design consideration is lifecycle risk. Because NXP lists MC9S08GT60ACFDE as NRND, engineers should avoid committing it to new designs unless NXP confirms availability and lifecycle support. Existing production equipment may continue to use the part subject to supply-channel verification. This page consolidates distributor listings, package information, lifecycle status, sourcing data, and application guidance. It also distinguishes verified drop-in alternatives from related S08 devices that are not automatically pin-compatible, helping engineers assess replacement risk without changing the embedded architecture unnecessarily.

MC9S08GT60CFDE - 8-Bit 40MHz S08 MCU 60KB Flash | NXP

The NXP Semiconductors MC9S08GT60CFDE is an 8-bit S08 CISC microcontroller with 60KB Flash program memory, 4KB RAM, and a 40MHz CPU core, housed in a 48-pin QFN-EP (HVQCCN, 7x7 mm) package. It operates from 2.5V/3.3V supply rails and offers 39 general-purpose I/O pins along with on-chip peripherals including PWM, LVD, POR, WDT, plus I2C, SCI, and SPI connectivity. The device targets industrial-grade embedded applications requiring deterministic 8-bit performance and small footprint integration. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (Flash/ROM), data memory (RAM), and I/O peripherals on a single die. The S08 family uses a CISC (Complex Instruction Set Computer) architecture with the HCS08 core, succeeding the legacy HC08 family. Within the broader hierarchy, the S08 sits under: microcontroller -> embedded processor -> semiconductor device. Compared with 32-bit Cortex-M devices, S08 microcontrollers trade raw throughput for cost, deterministic interrupt latency, and ultra-low static power consumption, making them preferred in cost-sensitive, latency-bound, or battery-aware designs. Key features of the MC9S08GT60CFDE include 60KB on-chip Flash with in-application reprogrammability, 4KB SRAM, an internal clock generator with trimming, multiple timer/PWM modules, an analog-friendly package with an exposed thermal pad, and built-in safety peripherals (LVD, POR, COP watchdog). The 48-pin QFN-EP package exposes enough GPIO (39 pins) for typical human-interface, motor-control, and sensor-hub designs. Industrial-grade operating temperature range (-40C to +85C minimum) makes the part suitable for factory and automotive cabin environments. Technically, the HCS08 core executes most instructions in 1-2 bus cycles and supports a BDM (Background Debug Mode) interface for in-circuit programming and debug. The on-chip Flash uses an embedded EEPROM-style array with security lock bits to protect intellectual property. The MC9S08GT60CFDE differs from the GT32 variant in memory density (60KB Flash vs 32KB Flash) and from GT16 in scaling — all share the S08 core and the 48-QFN-EP package, enabling family-up firmware reuse. Typical applications include industrial motor control (small BLDC, stepper drivers), appliance and white-goods human-interface modules, automotive body-electronics accessories, sensor-hub front-ends, and consumer remote controls. The combination of PWM, SCI/SPI, and I2C makes it well-suited as a bridge controller between a sensor network and a higher-level host. In low-power designs, the on-chip peripherals allow the CPU to remain in wait/stop modes while timers and interrupts handle event-driven wakeups. When designing with the MC9S08GT60CFDE, ensure the exposed thermal pad is soldered to a copper pour of at least 1 square inch to keep junction temperature in spec for continuous high-CPU-load scenarios. Designers should also evaluate the GT32CFDE variant (32KB Flash) for cost reduction if application code is small enough — both share the same 48-QFN-EP footprint, easing PCB reuse.

MC9S08GT8ACFCE - 40MHz 8KB Flash 8-bit MCU | NXP

The NXP Semiconductors MC9S08GT8ACFCE is a general-purpose 8-bit S08GT microcontroller operating at up to 40 MHz, with 8 KB of Flash memory, 34 I/O ports, and a 32-lead no-lead package identified by the source data as HVQCCN in a 5 mm by 5 mm square format. Its supply-voltage range is 1.8 V to 3.6 V. The enhanced S08 core uses the HCS08 instruction set with an added BGND instruction and supports up to 32 interrupt and reset sources. 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.

It targets single-phase electric, gas and water flow metering applications with two independent 16-bit SAR analog-to-digital converters (ADCs), a programmable delay block, and a pulse counter with automatic sensor decoding. An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, RAM, non-volatile program memory (Flash), peripheral I/O, and interrupt logic onto one silicon die. Within the broader taxonomy, the MC9S08GW32CLH belongs to the hierarchy: 8-bit MCU -> microcontroller -> microprocessor -> integrated circuit -> semiconductor. The S08 core uses an enhanced Harvard architecture and runs the same instruction set as the legacy HC08, giving designers a stable, well-documented software platform with modern peripherals. Key features include 32 KB (32K x 8) Flash program memory, two on-chip 16-bit SAR ADCs with hardware sequencer, an LCD driver controller suitable for multi-digit metrology displays, and a rich connectivity set including I2C, LINbus, SCI (UART) and SPI. The device includes PWM channels for switching transducers, an LCD controller, and a watchdog timer (WDT) for safety-critical metering functions. The MC9S08GW combines a low-power S08 core with metrology-grade analog front ends - the two 16-bit SAR ADCs are differential and can pair with shunt resistors or current transformers for active and reactive energy measurement. The built-in pulse counter with automatic decoder enables direct interface to gas and water meter pulse outputs, while the LCD driver removes the need for an external display controller in cost-sensitive meter designs. Typical applications include single-phase electric meters, gas flow meters, water flow meters, and other low-power instrumentation panels with LCD readouts. The 64-LQFP footprint also gives enough I/O for industrial sensor hubs and home energy displays. When designing with this part, ensure the ADC reference and shunt resistor layout follow metrology PCB guidelines to keep measurement error below the 0.5% accuracy class. Provide a low-impedance ground plane under the analog supply pins to prevent switching noise from coupling into the ADC input.

MC9S08GW64CLH - S08 8-bit MCU, 64KB Flash, 20MHz | NXP

The NXP Semiconductors MC9S08GW64CLH is an 8-bit microcontroller based on the proven S08 core, delivering 64KB of Flash memory, 20MHz bus operation, and dual independent 16-bit SAR ADCs in a 64-pin LQFP (10x10 mm) package. It is purpose-built for utility metering: the integrated pulse counter with automatic sensor decoding targets gas and water flow meters, while the dual-ADC architecture with programmable delay block supports single-phase electric metering. An 8-bit microcontroller (MCU) is a single-chip computer integrating a processor core, memory, and peripherals on one die. Within the power management and embedded control hierarchy, metering MCUs like the S08GW family sit between general-purpose 8-bit MCUs and dedicated metering ASSPs, offering meter-specific peripherals without sacrificing general I/O flexibility. Key features include the S08 core running at up to 20MHz, 64KB (64K x 8) Flash with in-application reprogramming, a flexible clock system with FLL (frequency-locked loop) supporting FEI, FEE, FBE, FBI, FBELP, and FBILP modes, and two independent 16-bit SAR ADCs. A programmable delay block ties ADC sampling to flow-pulse events, enabling accurate quasi-synchronous sampling of pressure and temperature for gas-density compensation. The device integrates typical metering peripherals: pulse counters with automatic quadrature/sensor decoding for reed, Hall, or optical flow sensors, plus serial communication (SCI/SPI/I2C-class peripherals on the S08 platform) for protocol handling in M-Bus, RF, and optical-head meter architectures. Low-power wait/stop modes support battery-powered water and gas meters with multi-year service life. Typical applications are gas flow meters, water flow meters, single-phase electric energy meters, and heat-cost allocators. The dual-ADC architecture allows simultaneous sensing of voltage and current channels in single-phase energy measurement. Design consideration: when the FLL reference source, reference divider, or trim value changes, or when moving between FLL-disabled and FLL-enabled modes, the clock specification applies per the manufacturer datasheet; allow settling time in software. If a crystal or resonator is used as the reference, ensure it is already running before mode transitions.
