MC9S08RG60FG - 8-Bit 8MHz 60KB Flash MCU, 44-LQFP | Motorola
MPN： MC9S08RG60FG ✓ 啟用中MC9S08RG60FG 概覽
A microcontroller is a complete single-chip computer: a CPU core, program memory, data memory, clocking, and on-chip peripherals integrated onto one die. The S08 family from Motorola is an 8-bit architecture aimed at cost-sensitive embedded control tasks such as consumer appliances, small motor drives, keypads, lighting controllers and simple sensor nodes. In the system hierarchy a microcontroller sits above a microprocessor only in integration, not in compute power: it trades raw speed for low power, low cost, and deterministic real-time behaviour.
The MC9S08RG60FG is built around the S08 8-bit core operating at up to 8 MHz, with 60K x 8 bytes of on-chip flash for in-circuit programmability. Its wide 1.8 V to 3.6 V supply span allows the same part to run directly from a single Li-ion cell, a 3 V coin cell, or a regulated 3.3 V rail, and the 44-LQFP package with a 10 x 10 mm body keeps the footprint compact enough for small consumer appliances and portable instruments.
Because flash is on-chip, application firmware can be re-programmed in the field through the device's serial programming interface, which removes the need for an external EEPROM or bootloader in many designs. This also protects intellectual property more effectively than mask-programmed ROM, while keeping the bill of materials to a single active device plus a decoupling network.
Typical uses include household appliance controllers, small brushless and stepper motor sub-systems, lighting and dimming modules, battery-powered measurement instruments, remote keypads, and general-purpose industrial control nodes where an 8-bit core with 60 KB of flash is ample for firmware of several thousand lines.
When laying out the board, keep the decoupling capacitors as close as practical to the supply pins and route the clock and reset nets away from switching nodes. Because the 8 MHz bus speed is modest, flash wait states are not a concern, but brownout behaviour during slow supply ramps still needs verifying against your power source.

典型應用
MC9S08RG60FG 適用於 6 應用s: Household Appliance Control Boards, Battery-Powered Portable Instruments, LED Lighting and Dimming Modules, Small Motor and Fan Control, Industrial Sensor Nodes and Condition Monitoring, Keypads, Human Interface and Access Panels.
Household Appliance Control Boards
The MC9S08RG60FG suits appliance controllers because 60 KB of on-chip flash comfortably holds motor sequencing tables, sensor conditioning code and a user-interface state machine, while the 1.8 V to 3.6 V operating range allows direct operation from rectified low-voltage rails. At an 8 MHz bus speed the S08 core executes the real-time control loops for washing machines, dishwashers or small kitchen appliances without an external processor. Because the program memory is flash, firmware revisions for different product variants can be programmed in circuit at the end of the production line without changing the board. The 44-LQFP (10 x 10 mm) package leaves generous pin access for keypad scanning, triac drive and relay outputs.

Battery-Powered Portable Instruments
For handheld meters and portable test gear, the MC9S08RG60FG's 1.8 V to 3.6 V supply range covers a single alkaline cell or a single Li-ion cell directly, which removes boost circuitry and reduces board area. The 60 KB of flash provides room for calibration tables, log buffers and multi-range measurement firmware, and the 8 MHz S08 core keeps acquisition timing deterministic. The 44-LQFP package is comfortable for hand-soldering in low-volume builds, and the wide supply window tolerates the voltage profile of a fresh cell through to near-discharge operation. Confirm the low-voltage brownout and sleep-mode currents from the manufacturer datasheet when finalising the power budget.
推薦
LED Lighting and Dimming Modules
LED drivers benefit from the MC9S08RG60FG because dimming algorithms, colour mixing tables and open-protocol control stacks such as DALI or DMX occupy real memory, and 60 KB of flash removes the need for an external EEPROM. The 8 MHz S08 core is fast enough to service PWM generation and current-regulation feedback loops, while the 1.8 V to 3.6 V range maps naturally onto low-voltage constant-current LED architectures. The 44-LQFP (10 x 10 mm) footprint keeps the controller compact next to the LED driver stage. Use the peripheral and timer assignment tables in the manufacturer datasheet to map PWM channels to the LED strings.
推薦
Small Motor and Fan Control
The MC9S08RG60FG targets small brushless DC fan, stepper and simple DC motor subsystems where the 8-bit S08 core can execute commutation and speed-control loops at an 8 MHz clock. Sixty kilobytes of flash is ample for multi-speed tables, stall-recovery logic and low-speed closed-loop control, and the wide 1.8 V to 3.6 V supply range allows the MCU to sit beside a motor driver running from the same rail. The 44-LQFP package provides enough pins for encoder inputs, Hall sensing and gate-drive control of an external MOSFET stage. Keep switching-node currents away from the MCU supply and reference planes during layout.
推薦
Industrial Sensor Nodes and Condition Monitoring
Remote sensor nodes benefit from the MC9S08RG60FG because 60 KB of flash allows on-board filtering, threshold logic and a compact protocol stack to run on a single low-cost device. The 1.8 V to 3.6 V operating range supports both 3.3 V industrial bus nodes and battery-backed installations, and the 8 MHz core gives deterministic sampling timing for vibration, temperature and level monitoring. The 44-LQFP (10 x 10 mm) package is compact for DIN-rail or enclosure-mounted nodes, and flash programmability means field firmware updates are possible without desoldering. Verify the temperature grade and any industrial qualification requirements against the datasheet before using the part in harsh environments.
推薦
Keypads, Human Interface and Access Panels
The MC9S08RG60FG is a natural fit for keypad scanners, door access panels and small user-interface modules where debounce logic, keypad mapping, display driving and communication are combined in one device. Sixty kilobytes of flash removes the need for an external memory when supporting multiple languages, log buffers or a graphical menu structure, and the 8 MHz clock gives ample headroom for scanning loops. The 1.8 V to 3.6 V supply range fits both 3.3 V and single-cell powered panels, while the 44-LQFP package keeps the board compact behind a keypad overlay. Plan the ground return path carefully so that keypad scan currents do not inject noise into the MCU supply.

主要差異化特點
- Largest on-chip flash in the 44-LQFP S08 drop-in family (對比MC9S08RG32FG)
- Broader logic peripheral set than the plain RG variant (對比MC9S08QE32CTG)
- Pin-compatible with same-package S08 alternatives for emergency substitution (對比MC9S08SG32FG)
- Field-reprogrammable flash instead of mask ROM (對比MC9S08QE32CTG)
設計說明
Place the device-side supply decoupling capacitor directly between the VDD and VSS pins, with the ground termination at the capacitor rather than routed back to the board edge. For an 8 MHz S08 design, a 100 nF ceramic in parallel with a 1 uF to 4.7 uF bulk capacitor is a practical starting point for the 1.8 V to 3.6 V supply range. Keep the VSS return path a continuous plane under and around the LQFP-44 body so that return currents from the switching peripherals do not share the sensitive reference path with the core.
The MC9S08RG60FG is an 8-bit part clocked at up to 8 MHz, so signal-integrity demand is modest, but the 44-LQFP (10 x 10 mm) footprint has a 0.5 mm lead pitch and requires careful escape routing. Fan out the power pins on all four sides, keep the clock and reset traces short and away from any motor gate-drive or relay-coil switching nets, and provide a solid ground pour beneath the package. If the board also carries an external EEPROM or serial transceiver, place them at the opposite end of the PCB from the MCU to limit shared-impedance coupling.
Two mistakes recur with this part. First, substituting a lower-flash sibling purely on the assumption that 60 KB is unnecessary: the MC9S08RG32FG and MC9S08QE32CTG provide only 32 KB, so the firmware must be recompiled and re-mapped before the substitution is valid. Second, assuming that a bare 44-LQFP footprint matches every S08 variant, since family members also exist in other lead counts and package sizes. Always check the ordering-information table and the mechanical drawing in the manufacturer datasheet before approving any alternate part number on a released design.
In battery-fed designs the 1.8 V lower operating limit of the MC9S08RG60FG deserves attention because a single alkaline cell can fall below 1.8 V under load near end of life. Either size the cell for the worst-case loaded voltage, add a low-dropout booster, or accept operation down to the point where brownout resets the MCU. Estimated: with a 3.0 V cell and a 2.0 V brownout threshold, usable capacity is roughly 33 percent lower than for a 1.0 V brownout threshold, so the cutoff choice directly affects run time.
