MC9S08AC96CL - 8-Bit 40MHz 96KB Flash MCU | NXP

The NXP MC9S08AC96CL is an 8-bit HCS08 S08 microcontroller with a 40 MHz maximum clock, 96 KB of flash memory, and an 80-lead LQFP package measuring 14 mm by 14 mm. It is designed for embedded control systems requiring integrated communications, automotive support, and moderate on-chip memory. A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and input/output interfaces on one device. The HCS08 S08 family belongs to the 8-bit MCU hierarchy and is commonly used for cost-sensitive control, monitoring, communication, and actuator-control designs. Its peripherals let a product perform useful tasks without relying on a separate processor for basic real-time control. The verified distributor listing identifies the MC9S08AC96CL as an HCS08 S08 microcontroller operating up to 40 MHz with 96 KB of flash memory organized as 96K x 8. The NXP listing for the closely identified MC9S08AC96CLKE additionally states that this family variant provides 4 KB of RAM, SCI, SPI, IIC, and integrated CAN support for automotive applications. These interfaces make the device applicable to distributed control systems that need both serial connectivity and CAN communications. The 80-LQFP package provides a higher pin count than small-outline packages and offers more exposed connection options for peripheral signals, power, debugging, and communications. Its 14 mm by 14 mm body dimensions should be considered during PCB footprint selection, assembly planning, and thermal assessment. Because the supplied verified data does not include the complete electrical limits, pin-level assignments, or memory map, those details must be confirmed against the manufacturer datasheet before a new design is released. Typical application directions include automotive body and chassis electronics, CAN-connected industrial controllers, communication hubs, data-acquisition equipment, and general embedded automation. The 40 MHz clock supports timely execution of control logic, while the 96 KB flash capacity provides room for firmware and application code. The available SCI, SPI, IIC, and CAN functions support both point-to-point and bus-oriented peripherals when those details are confirmed for the exact ordering option. Designers should verify the exact package pinout, voltage limits, clock configuration, reset requirements, and peripheral multiplexing in the manufacturer datasheet before layout or firmware deployment. For a replacement decision, do not rely only on the base MC9S08AC96 designation: the CL suffix, package, temperature range, qualification status, and supported peripheral set must all match. This page combines distributor specifications, datasheet references, sourcing links, and practical design guidance to support that verification process.

MC9S08AC96CLKE - 40MHz 96KB Flash 8-Bit MCU | NXP
MC9S08AC96CLKE

MC9S08AC96CLKE - 40MHz 96KB Flash 8-Bit MCU | NXP

The NXP Semiconductors MC9S08AC96CLKE is an 8-bit HCS08 S08AC-series microcontroller with a 40 MHz maximum clock, 96 KB of flash program memory, and an 80-LQFP package measuring 14 mm by 14 mm. The verified distributor data identifies 38 I/O ports, while another supplied source lists 69 I/O, creating an unresolved source discrepancy that must be checked against the manufacturer datasheet before design release. A microcontroller is a programmable semiconductor that integrates a CPU core, nonvolatile program memory, working memory, I/O ports, and peripherals on one device. The HCS08 CPU belongs to the MCU and embedded-controller hierarchy: firmware executes from flash, peripherals connect the controller to external hardware, and general-purpose I/O supports digital sensors, switches, indicators, and actuators. This makes the device suitable for compact embedded-control systems rather than host computing workloads. The documented headline resources include an S08 8-bit processor core, 40 MHz clock speed, 96 KB flash, and a supply-voltage range of 2.7 V to 5.5 V. A supplied technical source also identifies 6K x 8 RAM, I2C, LINbus, SCI, SPI, low-voltage detection, power-on reset, PWM, and a watchdog timer. These interfaces make the MCU suitable for communication bridges, industrial modules, motor-control assistance, and general embedded-control products. The S08AC family combines 8-bit and 32-bit pin-compatible device pairs within the Flexis series. That ecosystem context is useful when upgrading controller complexity, but it does not prove that every family member is a drop-in replacement for MC9S08AC96CLKE. Firmware, memory capacity, peripheral mapping, clocking, electrical limits, and package pins must be compared before substitution. Typical installations place the controller between power regulation and application-specific interface circuitry. I2C or SPI can connect sensors and memories, SCI can support external data links, timer and PWM resources can drive indicators or actuators, and the watchdog can improve recovery from firmware faults. Designers must also account for decoupling, clock stability, programming access, unused pins, and reset behavior. For new production, lifecycle planning is especially important because the official NXP result explicitly displays an End of Life overview. Existing embedded products may continue using the part, but new designs should confirm procurement timing, last-time-buy conditions, firmware support, and any approved replacement before committing. This page distinguishes verified facts from unresolved parameters rather than assuming a universal replacement. This page consolidates manufacturer lifecycle information, distributor specifications, package details, sourcing data, and engineering cautions that are not presented together on a manufacturer product page. It also explains why package similarity alone is insufficient for declaring a pin-compatible substitute, helping engineers make a safer sourcing decision.

MC9S08AC96MLKE

MC9S08AC96MLKE - 40MHz 96KB Flash S08 Microcontroller | NXP

NXP Semiconductors MC9S08AC96MLKE is an 8-bit S08 microcontroller with a 40 MHz maximum clock, 96 KB of flash program memory, and a 3.3 V/5 V supply range in an 80-pin LQFP package. Verified listings also describe an S08 core, an LCD driver, an ADC, and an integrated temperature sensor for embedded control, industrial, and automotive-related designs. A microcontroller is a programmable system-on-chip that combines a processor core, nonvolatile program memory, volatile working memory, peripherals, and input/output in one package. The S08 belongs to the 8-bit MCU hierarchy and is positioned below higher-performance 16-bit and 32-bit processors. It is intended for embedded products that need deterministic control, serial communications, analog measurement, and flexible firmware updates without the complexity of a larger processor architecture. The verified 40 MHz clock provides processing headroom for control loops and communication service routines, while 96 KB of flash stores application code and configuration data. The 80-LQFP package exposes substantially more I/O than a small-package MCU, making the device useful where multiple sensors, actuators, displays, or serial interfaces are required. The verified data identifies I2C, LINbus, SCI, SPI, PWM, watchdog, low-voltage detection, and power-on reset functions among the peripheral capabilities. Supply operation from 2.7 V to 5.5 V supports both 3.3 V and 5 V system designs, subject to all peripheral and timing constraints in the manufacturer documentation. The integrated LCD driver is especially relevant to local human-machine interfaces, while the ADC and temperature sensor support measurement-oriented products. Exact RAM content, complete pin assignment, ADC resolution, timer dimensions, and electrical timing values should be confirmed in the datasheet before layout or firmware release. Typical applications include industrial controllers, automotive accessory modules, keypad interfaces, instrument panels, serial gateways, data-acquisition units, and compact embedded control panels. The large package provides routing flexibility and useful I/O access, but it occupies more PCB area than a QFN device. Designers should preserve all required decoupling, programming-test access, analog grounding, and package thermal considerations documented by NXP. A critical sourcing issue is lifecycle ambiguity: the NXP search result contains an End of Life notice, while several distributor snippets identify the exact orderable MPN as active. Confirm the current PCN and purchasing status with NXP or an authorized distributor before committing to production. This page combines verified source specifications, procurement data, and engineering cautions while clearly marking details that were not established by the supplied sources.

MC9S08AW16CFDE

MC9S08AW16CFDE - 16KB Flash 40MHz HCS08 8-bit MCU | NXP

The NXP MC9S08AW16CFDE is an 8-bit HCS08-family microcontroller (MCU) featuring an enhanced S08 core, 16 KB of on-chip Flash, 40 MHz maximum CPU clock, and 38 general-purpose I/O pins, packaged in a 48-pin QFN-EP (7x7 mm, 0.5 mm pitch). It belongs to the MC9S08AW60/AW48/AW32/AW16 family of low-cost, high-performance HCS08 microcontrollers intended for industrial and automotive applications. The part operates from a 2.7 V to 5.5 V supply and supports a 20 MHz internal bus frequency for the HC08 instruction set with the added BGND instruction and single-wire background debug mode (BDM). An 8-bit microcontroller is a microprocessor with an internal 8-bit data path, on-chip program and data memory, and integrated peripherals such as timers, ADCs, and communication blocks. The HCS08 family evolved from the legacy HC08 architecture by adding the BGND instruction and a single-wire background debug mode, which enables non-intrusive in-circuit debugging without consuming a limited pin resource. The MC9S08AW16CFDE sits at the entry point of the AW family and is widely used in cost-sensitive embedded designs that need predictable real-time performance, generous Flash for application code, and automotive-grade robustness. Key features include 16 KB Flash program memory, 1 KB SRAM, a 10-channel 10-bit ADC, two SCI (UART) modules, one SPI, one IIC, a 6-channel 16-bit timer/PWM, an analog comparator, and an internal clock generator with FLL. The QFN-EP package provides an exposed thermal pad that lowers thermal resistance to the PCB, enabling reliable operation at the full industrial temperature range. The device supports both background debug mode and on-chip in-application programming, simplifying firmware development and field updates. From an architectural perspective, the HCS08 core executes the standard HC08 instruction set with a 20 MHz internal bus (half of the 40 MHz CPU clock), which keeps power consumption low while preserving deterministic interrupt latency. The integrated FLL-locked internal clock eliminates an external crystal for many use cases, while the ROM-resident monitor plus single-wire BDM interface removes the need for an expensive emulator. The part also includes a watchdog timer, low-voltage detect, and a real-time interrupt for periodic wake-ups. Typical applications include automotive body electronics such as seat controllers and lighting modules, industrial sensor conditioning and motor control front ends, white goods and appliance control boards, HVAC damper and fan controllers, and low-end consumer devices. The wide 2.7 V to 5.5 V supply range also makes it suitable for battery-powered instrumentation that runs directly from a single Li-ion cell (3.0 V to 4.2 V). The S08AW family is supported by NXP's CodeWarrior IDE and the newer Eclipse-based S32 Design Studio plug-ins, enabling rapid prototyping and code reuse across the AW family. When designing with this MCU, place decoupling capacitors (typically 100 nF plus 4.7 uF bulk) within 5 mm of every supply pin, route the exposed pad to a continuous ground copper pour, and keep the RESET pin pulled up through a 4.7 kohm resistor. Programming via the BKGD pin requires an external pull-up on the BKGD line; a series resistor near the MCU is recommended for in-circuit programming reliability. Plan the Flash endurance budget (typically 100 K cycles) and code size carefully since 16 KB is small for modern stacks.

All family members share the same S08 core, peripheral set and package options, differing primarily in Flash memory size, which allows firmware-scalable designs and footprint-compatible upgrades to 32KB, 48KB or 60KB. The AW series supports both industrial and automotive industry requirements, and the device is specified with package MO-220VKKD-2 (7x7/10x10 mm body, 0.50 mm pitch per JEDEC outline cited in distributor data). Typical applications include HVAC control systems - the part is a documented direct replacement controller in HVAC platforms from 2005-2015 - home appliances, industrial sensors, motor control panels, and automotive body electronics. Design consideration: because NXP lists this part as NRND (Not Recommended for New Designs), new designs should evaluate the newer S08P or S08PT families, while existing designs can keep sourcing the AW family or its pin-compatible higher-memory siblings.

Decouple VDD with a 100nF ceramic capacitor placed within 5 mm of each supply pin, and solder the exposed pad (EP) to a thermal pad with thermal vias for adequate heat spreading in industrial-temperature designs. Be aware that NXP has marked this part NRND (Not Recommended for New Designs), so consider the related S08AW family members or S08QE/S08AC successors for new product introductions.

MC9S08AW60CFGE - 8-bit S08 MCU, 60KB Flash, 40MHz | NXP

The NXP MC9S08AW60CFGE is an 8-bit HCS08 microcontroller with a 40 MHz HCS08 CPU (20 MHz internal bus frequency), 60 KB flash memory, 2 KB RAM, and a 44-pin LQFP (10x10 mm) package. An 8-bit microcontroller is an integrated circuit that contains a processor core, memory, and programmable peripherals on a single chip, executing instructions on 8-bit data words. Within the embedded systems hierarchy, the MCU sits at the device level of the broader microcontroller family: HCS08 core -> S08 family -> Freescale/NXP 8-bit MCU -> semiconductor IC. MCUs like the S08AW are used where cost, low pin count, and sufficient performance matter more than raw processing power. Key features of the MC9S08AW60 include the enhanced HCS08 core with HC08 instruction set compatibility plus the added BGND instruction, single-wire background debug mode (BDM) interface for low-cost emulation and flashing, 8-channel 10-bit ADC, and a supply voltage range of 2.7V to 5.5V, supporting both 3.3V and 5V systems. The part is available in industrial and automotive-qualified contexts per NXP product information, with 38 general-purpose I/O lines on this package variant. Architecturally, the S08AW family uses flash-based program memory with in-application programming capability, and the on-chip peripherals include timer/PWM modules, serial communication interfaces (SCI, SPI), and an IIC bus controller, enabling single-chip designs for measurement and control tasks without external components. Typical applications include automotive body electronics (window lifters, lighting control, cluster functions), industrial control and motor-adjacent logic, appliance control boards, and low-cost human-machine interfaces. The wide 2.7V to 5.5V operating range and robust I/O make it well suited to harsh electrical environments. A key design consideration is lifecycle status: NXP lists this part as NRND (Not Recommended for New Designs), so new projects should evaluate family successors, while existing designs can continue sourcing through authorized channels. This page adds value beyond the datasheet by consolidating drop-in alternatives, lifecycle guidance, comparison tables, and design notes sourced from NXP and distributor data verified as of 2026-10-18.
