MC9S08RG32CFGE Descripción general

The NXP (formerly Freescale) MC9S08RG32CFGE is an 8-bit HC08/S08 CISC microcontroller with 32 KB of on-chip Flash and 2 KB of RAM, housed in a 44-pin LQFP package operating from a 2.5 V or 3.3 V supply. It belongs to the S08RG family of low-power, cost-optimized microcontrollers designed for industrial-grade embedded designs.

Background: An 8-bit microcontroller (MCU) is a single-chip computer that integrates an 8-bit CPU core, program memory (Flash), data memory (RAM), and a range of peripherals (timers, ADC, communication ports). Within the broader taxonomy it sits below 16-bit/32-bit MCUs and ARM Cortex-M parts, but remains attractive in cost-sensitive and pin-count-constrained designs. The S08 line is Freescale/NXP's HC08 successor, emphasizing a CISC instruction set, linear memory map, and ultra-low-power modes that compete head-to-head with Microchip PIC and Atmel AVR families.

Key features highlighted in the verified data include an 8 MHz internal bus interface, 32 KB of Flash program memory, 2 KB of RAM, an industrial temperature grade, gull-wing LQFP-44 surface-mount leads, and a tray packaging format. The part is qualified to industrial operating ranges and uses a 3.3 V (with 2.5 V core) supply arrangement typical of S08 devices.

Architecturally the MC9S08RG32CFGE integrates the S08 CISC core with an on-chip Flash controller, run-mode and wait-mode clocking, plus standard S08 peripherals such as timers, an ADC, and serial communication blocks. Compared with higher-end ColdFire or ARM parts it sacrifices raw performance for a smaller die, lower cost, and easier toolchain adoption via CodeWarrior and the newer Eclipse-based S08 IDE.

Typical applications include industrial control nodes, appliance control boards, low-end sensor hubs, consumer electronics sub-MCUs, and LED lighting controllers. The 32 KB Flash comfortably supports state machines, ModBus or CANopen slave stacks, and small UI loops. The 44-LQFP footprint gives enough I/O for keypad scanning, motor-driver PWM, and multiple serial channels.

When designing with this part, plan the Flash partitioning and vector remap early - the S08 has fixed interrupt vectors that occupy the top of the Flash. Leave a small bootloader area if you intend field updates, and budget stack/heap RAM against the 2 KB ceiling.

Aplicaciones típicas

MC9S08RG32CFGE es adecuado para 6 aplicacións: Industrial Control Nodes, Appliance Control Boards, Low-End Sensor Hubs, Consumer Electronics Sub-MCUs, LED Lighting Controllers, Automotive Body Electronics (AEC-Q100 Not Qualified).

🏭

Industrial Control Nodes

The MC9S08RG32CFGE's 32 KB Flash and 2 KB RAM comfortably host ModBus RTU slave or simple proprietary field-bus stacks for industrial sensor and actuator nodes. Its 44-LQFP footprint exposes enough I/O for digital input sampling, PWM-driven motor commands, and an RS-485 or RS-232 link. Industrial temperature grade plus the mature S08 CISC core make the part a long-life candidate for factory-floor PLCs and remote I/O.

🏭

Appliance Control Boards

White-goods designs (washing machines, dishwashers, microwave user interfaces) frequently pair an S08 MCU with a keypad matrix, a TRIAC or relay driver, and a 7-segment or LCD panel. The MC9S08RG32CFGE's 36+ GPIO lines handle keypad scanning, LED/relay drive, and a UART link to a Wi-Fi/BLE module without external I/O expanders. The 8 MHz core plus Freescale's low-power wait modes keep standby current acceptable for ENERGY STAR targets.

🧩

Low-End Sensor Hubs

When a sensor hub needs to aggregate analog channels and forward data over UART/SPI, the MC9S08RG32CFGE offers a cost-effective solution. Its 8-channel ADC (typical for the S08RG family) handles thermistor, photodiode, or 4-20 mA front-ends, while the S08 core runs calibration and average loops in firmware. Industrial grade plus industrial EMI tolerance suit factory or building-automation deployments.

📱

Consumer Electronics Sub-MCUs

Designers use a low-cost 8-bit S08 as a 'housekeeping' MCU next to a higher-end application processor in toys, audio docks, and wearables. The MC9S08RG32CFGE handles battery charging, button debouncing, LED breathing effects, and power-key sequencing while the main CPU stays asleep. The LQFP-44 form factor drops easily onto a 2-layer consumer PCB and supports hand or reflow soldering.

💡

LED Lighting Controllers

Commercial and architectural LED drivers need an MCU that can run DMX-512 or DALI receive logic, dim curves, and thermal foldback. The MC9S08RG32CFGE's 2 KB RAM and 8 MHz core suffice for a single DMX universe at 250 kbps with channel-by-channel PWM. The 44-LQFP package exposes timer/PWM channels needed for 4- to 8-channel high-current LED strings paired with external MOSFET drivers.

🚗

Automotive Body Electronics (AEC-Q100 Not Qualified)

Although the MC9S08RG32CFGE is rated for industrial (not automotive) temperature and is not AEC-Q100 qualified, designers have used S08RG parts in non-safety body modules like seat controllers, mirror adjusters, and HVAC panel interfaces. For new designs that require AEC-Q100, prefer the S08AC or S12Z families; the MC9S08RG32CFGE remains a viable cost-down option for non-safety nodes with appropriate derating.

What is the program memory size of the MC9S08RG32CFGE?
The MC9S08RG32CFGE integrates 32 KB of on-chip Flash program memory organized as 32K x 8 bits, according to the verified manufacturer datasheet. This is sufficient for state-machine firmware, small protocol stacks (ModBus RTU slave, LIN), and simple UI logic. Designers should reserve a bootloader region if field updates are planned, since S08 vectors occupy the top of Flash.
Is the MC9S08RG32CFGE still in production?
The MC9S08RG32CFGE is reported as obsolete / end-of-life per the cross-reference data fetched on 2026-10-18. Heisener still shows 4,736 pieces of stock, but production allocations have ended. Engineers should plan for last-time-buy windows or evaluate cross-brand drop-in replacements listed on this page before new design-ins.
What package does the MC9S08RG32CFGE use?
The MC9S08RG32CFGE ships in a 44-pin LQFP package measuring 10 mm x 10 mm with gull-wing leads, per the verified Vyrian and DigiKey Marketplace listings. LQFP-44 gives roughly 36 usable I/O lines, depending on how many peripherals the application activates. The package is tray-packed for low-volume industrial assembly.
What is the operating voltage range of the MC9S08RG32CFGE?
The verified data lists the MC9S08RG32CFGE as a 2.5 V / 3.3 V part (typical industrial supply). The exact minimum/maximum operating voltage was not present in the supplied web snippets, so it is flagged as [DATA_NEEDED: full VDD range]; consult the Freescale/NXP S08RG datasheet (document available via alldatasheet link on this page) for the precise min and max.
How much RAM does the MC9S08RG32CFGE have?
The MC9S08RG32CFGE provides 2 KB of on-chip RAM according to the Mouser listing. This RAM budget must cover stack, heap, and global variables, so it constrains the choice of RTOS or large buffers. For protocols that need more headroom, use a ring-buffer in Flash (XDATA) or upgrade to the S08RG 4 KB-RAM variant.
What is the CPU core of the MC9S08RG32CFGE?
The MC9S08RG32CFGE uses the NXP/Freescale HC08/S08 8-bit CISC core at up to 8 MHz internal bus speed, per the alldatasheet summary. The S08 instruction set is binary-compatible with legacy HC08 code and is supported by CodeWarrior (classic) and newer Eclipse-based S08 IDE plug-ins, plus GCC for ColdFire/S08 toolchains where available.
Where can I buy the MC9S08RG32CFGE today?
As of 2026-10-18, the MC9S08RG32CFGE is listed at Heisener (4,736 pieces in stock with quote-based pricing), DigiKey Marketplace via Rochester Electronics, Mouser (with datasheet/inventory links), and Octopart's distributor aggregator. Stock is finite because the part is obsolete; lead time is shown as 'to be confirmed' on Heisener with an estimated delivery window of Dec 11-16.
What is the price of the MC9S08RG32CFGE?
The MC9S08RG32CFGE has distributor-level reference pricing around $8.50 at qty 1, stepping down to approximately $5.55 at qty 1000, as of 2026-10-18. Heisener explicitly requires 'Request a Quote' because the part is obsolete, and DigiKey Marketplace reflects broker-stock pricing rather than factory pricing. Compare with cross-brand drop-in alternatives on this page for cost down.
What is the lead time for the MC9S08RG32CFGE?
Lead time for the MC9S08RG32CFGE is listed as 'To be Confirmed' on Heisener with an estimated delivery window of December 11-16 (2026) for expedited shipping, as of 2026-10-18. Because the part is obsolete, lead times can change weekly; for production runs, lock in last-time-buy quantities or pivot to a drop-in equivalent.
What is a drop-in replacement for the MC9S08RG32CFGE?
Drop-in, same-package pin-compatible replacements for the MC9S08RG32CFGE in LQFP-44 include the same-family S08RG variants such as MC9S08RG32CFGE (variant suffixes), plus the cross-reference STM8S207S6T3 family (LQFP-44, 32 KB Flash) called out by GlobalSpec. Note that cross-brand equivalents are NOT binary-compatible at the S08 core level - they require firmware recompilation even though the PCB footprint matches.
MC9S08RG32CFGE vs MC9S08AW32CPUE - which should I use?
The MC9S08RG32CFGE (S08RG, 32 KB Flash, 2 KB RAM, 44-LQFP) and the MC9S08AW32CPUE (S08AW, 32 KB Flash, LQFP-64) differ mainly in peripheral set and pin count. Choose MC9S08RG32CFGE when 32 KB Flash and 44 pins are enough and you value the lower cost; choose MC9S08AW32CPUE when you need additional timers, ADC channels, or communication ports. Both are NXP/Freescale S08 8-bit CISC devices and share toolchain support.
Can the STM8S207S6T3 replace the MC9S08RG32CFGE on the same PCB?
The STM8S207S6T3 (STMicroelectronics) is listed in cross-reference databases as a pin-/package-compatible LQFP-44 alternative to the MC9S08RG32CFGE, sharing 32 KB Flash-class memory and similar peripheral count. However, the STM8 uses an STM8 core and ST toolchain, not the S08 core and CodeWarrior - you must recompile firmware and revalidate interrupt vectors and peripheral register maps, even though the PCB footprint is the same.
Where do I download the MC9S08RG32CFGE datasheet PDF?
The MC9S08RG32CFGE datasheet is freely available at alldatasheet.com (174183/FREESCALE/MC9S08RG32CFGE, 234 pages), the FindIC mirror (1703 KB PDF), and the AiPCBA PDF mirror. NXP's official product page on nxp.com hosts the latest Freescale-authored revision under the MC9S08RG32 datasheet family. Always cross-check the document number against NXP's product page when qualifying a design.
Where can I find the MC9S08RG32CFGE pinout?
The MC9S08RG32CFGE pinout is documented in the LQFP-44 datasheet section on the official Freescale/NXP S08RG reference manual. The 44 pins map to one I/O port cluster, power/ground pairs, reset, background-debug mode (BKGD), and standard S08 peripheral pins. The package SVG diagram on this page (lqfp-44) visualizes the gull-wing lead layout; full per-pin multiplex tables come from the datasheet, not the web snippet.
What development tools support the MC9S08RG32CFGE?
The MC9S08RG32CFGE is supported by Freescale/NXP CodeWarrior for S08 (classic IDE), the Eclipse-based S08 plug-in IDE, P&E Micro ICD/BDM debuggers via the BKGD pin, and GCC for ColdFire/S08 toolchains where available. The on-chip background-debug mode (BDM) allows non-intrusive flash programming and single-wire debug, which keeps prototype bring-up simple.

Guía de selección

Choose the MC9S08RG32CFGE when you need a 44-LQFP, 8-bit S08 MCU with 32 KB Flash and 2 KB RAM for industrial-grade designs and you already have S08 firmware to leverage. Choose the same-family MC9S08RG32CFGER when you need tape-and-reel packaging for high-volume SMT assembly instead of tray. Choose the MC9S08AW32CFUE when you need more GPIO, timers, or ADC channels and can absorb a 64-LQFP footprint. Choose STM8S207S6T3 / STM8S207S6T3B as a cross-brand LQFP-44 drop-in alternative when the NXP part is unavailable - but budget time for firmware recompilation because the cores are different. For new designs, consider active S08 or S12 parts since the MC9S08RG32CFGE is obsolete and should be phased out of new design-ins.

Notas de diseño

Because the MC9S08RG32CFGE is obsolete (last verified 2026-10-18), do NOT start a new design-in without securing last-time-buy quantity or pre-qualifying a drop-in alternative. Cross-brand equivalents (STM8S207S6T3) share the LQFP-44 footprint but require a complete firmware recompile because the STM8 core is not binary-compatible with S08.

S08 interrupt vectors live at the top of Flash. If you plan a bootloader for field updates, reserve the top vector block in the linker script (PR_LIN and PR_HIG) and remap vectors into a bootloader section, otherwise in-application programming will overwrite the reset vector.

Configure the S08RG in wait mode between sensor reads to keep average current below industrial-embedded targets. Estimated: running 8 MHz active ~5 mA, wait mode ~50 uA typical - verify exact numbers against the Freescale/NXP MC9S08RG32 datasheet power-consumption table before committing to battery-life calculations.

Place the LQFP-44 decoupling capacitor (0.1 uF ceramic) within 50 mil of each VDD/VSS pair, and add a bulk 10 uF tantalum near the regulator input. The BKGD pin must be accessible on the PCB for in-circuit debugging via P&E Micro or P&E MULTILINK.
