MC9S08AC96CFUE - 8-bit MCU 96KB Flash 40MHz | NXP
MPN: MC9S08AC96CFUE ✗ Cuối đờiMC9S08AC96CFUE Tóm tắt
An 8-bit microcontroller is an integrated circuit that executes embedded control programs using a CPU processing 8-bit data words. Within the system hierarchy, it belongs to the embedded microcontroller family (MCU -> embedded processor -> semiconductor IC) and sits in NXP's S08 core family, part of the Flexis series where 8-bit and 32-bit devices share pin-compatible footprints, allowing engineers to migrate between performance tiers without PCB redesign.
Key features include 96KB (96K x 8) of flash program memory for large firmware images, 8KB of on-chip RAM, and a 40MHz bus-capable HCS08 core. The device integrates connectivity peripherals including I2C, LINbus, SCI, and SPI, plus low-voltage detection (LVD) and other system peripherals suited to automotive-adjacent and industrial designs. The 64-QFP surface-mount package supports standard SMT assembly.
Technically, the S08AC family uses the HCS08 Central Processor Unit architecture with flash memory rated for in-circuit reprogramming. The wide supply voltage window of 2.7V to 5.5V allows direct operation from 3.3V or 5V rails, simplifying mixed-system power design and improving noise margin in industrial environments.
Typical applications include industrial control, embedded automation, motor control, metering, IoT nodes, and low-power board designs, where the combination of large flash, rich serial connectivity, and 5V tolerance fits cost-sensitive control nodes.
Design consideration: this part is flagged End of Life by NXP, so new designs should plan a migration path to a supported S08 or Flexis successor, or secure last-time-buy stock.

Ứng dụng tiêu biểu
MC9S08AC96CFUE phù hợp cho 6 Áp dụngs: Industrial Control Systems, Motor Control, Metering and Smart Energy, Embedded Automation Nodes, IoT Sensor End Nodes, Low-Power Board Designs.
Industrial Control Systems
The MC9S08AC96CFUE fits industrial control nodes where a 40MHz 8-bit core handles deterministic scan loops and the 2.7V-5.5V supply range survives noisy 5V backplanes. Its 96KB flash accommodates protocol stacks and diagnostic code, while SCI/SPI links interface with operator panels and I2C connects local sensors. Used as the main controller on a PLC I/O daughter board, the MCU executes PID loops with PWM outputs and reports over SCI; the wide voltage window and LVD peripheral give robust brown-out behavior that discrete 3.3V-only MCUs lack in factory environments.
Được đề xuất
Motor Control
For small BLDC and brushed DC motor drives, the MC9S08AC96CFUE provides PWM outputs driven from a 40MHz bus, sufficient timer resolution for 20kHz-class switching, and SPI to talk to gate-driver or smart-power devices. The 5V-native I/O connects directly to hall sensors and current-shunt amplifiers without level shifting, and the 96KB flash stores commutation tables plus fault-logging firmware. Placed as the sole controller on a driver board, its deterministic S08 core keeps current-loop latency predictable; the trade-off versus DSP-class MCUs is lower math throughput on FOC algorithms.
Được đề xuất
Metering and Smart Energy
Energy meters benefit from the MC9S08AC96CFUE's combination of 96KB flash for tariff and metrology firmware, 8KB RAM for data buffering, and I2C/SCI links to metering front-ends and communication modules. Operating from 5V mains-derived supplies, its LVD and watchdog peripherals enforce safe restarts after brown-outs, a common field event in distribution grids. In a residential electricity meter, the S08 core samples the metrology IC over SPI, accumulates consumption, and drives an optical/IR communication port; the large flash also supports firmware field updates via the bootloader.
Được đề xuất
Embedded Automation Nodes
Distributed automation I/O - proximity-sense nodes, valve controllers, and conveyor counters - map well onto the MC9S08AC96CFUE's 38 I/O lines and LINbus/SCI connectivity. The 64-QFP 14x14mm package offers enough pins for switch inputs, relay drives, and status LEDs on a two-layer board, keeping BOM cost low. The S08 core executes scan-cycle logic at 40MHz with deterministic timing, and the 5V-tolerant I/O withstands industrial wiring transients better than 3.3V MCUs. Its main design constraint is the End of Life status, so volume automation programs should design in the S08AC128 pin-compatible variant.
Được đề xuất
IoT Sensor End Nodes
Battery-tolerant IoT end nodes use the MC9S08AC96CFUE's low-voltage operation down to 2.7V, letting the same board run from three alkaline cells or a 3.3V rail. The 96KB flash holds a full sensor-driver, packet-framing, and retry stack, while I2C attaches digital sensors and SPI attaches sub-GHz radios. In a typical node the S08 core wakes on LVD/IRQ, samples sensors over I2C, and hands packets to a radio over SPI, then sleeps between reports; the trade-off is the absence of modern ultra-low-power sleep currents found in newer Kinetis L parts.
Được đề xuất
Low-Power Board Designs
For compact boards where a single 5V supply powers everything, the MC9S08AC96CFUE removes regulator stages by accepting 2.7V-5.5V directly and integrates flash, RAM, and all serial peripherals on-chip, minimizing component count. The 64-QFP 14x14mm footprint routes on two layers with 0.5mm-pitch fanout. Designers typically use the S08 core for housekeeping, human-interface scanning, and protocol bridging between an SPI display and SCI host. Because NXP has flagged End of Life, new low-power boards should evaluate the pin-compatible S08AC128 or a Kinetis L device for supply continuity.

Ghi chú thiết kế
NXP lists the MC9S08AC96CFUE as End of Life with a discontinuance Product Change Notice. Before committing a new design, confirm the last-order date on the NXP PCN and evaluate the pin-compatible MC9S08AC128CFUE within the same S08AC family to avoid a forced redesign when stock disappears. For existing designs, size a last-time-buy against worst-case attrition plus field-repair needs.
The 2.7V-5.5V supply range lets the MCU run directly from 5V industrial rails, but decouple VDD/VDDA with 0.1uF ceramics at each pin plus bulk capacitance near the package. Enable the on-chip low-voltage detection (LVD) and configure its trip point for your rail so the watchdog resets cleanly during brown-outs instead of executing corrupted firmware from a marginally-powered flash.
The 64-QFP 14x14mm package fans out on a standard 0.65mm-pitch two-layer board with vias placed at pad toes. Keep the crystal/oscillator traces short and guard them with ground, since the 40MHz S08 bus is sensitive to layout-induced startup failures. Route SCI/LIN lines away from motor or relay switching nets; LINbus transceivers should sit close to the pin with their own local ground reference.
