MC9S08GT60CFD - 8-bit 40MHz S08 MCU 60KB Flash QFN48 | NXP
MPN： MC9S08GT60CFD ✓ 啟用中MC9S08GT60CFD 概覽
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and peripherals onto one silicon die. The HCS08 core is a CISC architecture that uses the HC08 instruction set with the added BGND instruction for background debugging. The MC9S08GT60CFD belongs to the S08GT family, which is a sub-family of the broader S08 microcontroller line within NXP's automotive and industrial MCU portfolio, characterized by low power consumption, integrated peripherals, and small form factors ideal for space-constrained designs.
Key features include 60 KB (60K x 8) of Flash memory, 4 KB of RAM, 39 general-purpose I/O lines, a 40 MHz maximum CPU frequency, support for up to 32 interrupt/reset sources, and software-selectable pullups on port pins when used as inputs. The internal pullup on the RESET and IRQ pin reduces external component count, lowering total BOM cost. Operating voltage is 2.5V or 3.3V, and the device includes an internal clock generator option.
The MC9S08GT60CFD uses a Harvard architecture with separate program/data bus structures and an enhanced HCS08 core that delivers approximately 1.6x the performance of the original HC08 at the same clock frequency. The integrated peripherals include timer/PWM modules, ADC, SCI/SPI/I2C serial interfaces, and a watchdog timer, providing flexible connectivity and control for motor control, sensor interfaces, and human-machine interface applications.
Typical applications include industrial control systems, white goods and home appliances, HVAC controls, security alarm systems, low-end consumer electronics, and sensor interface modules. The 48-QFN package with exposed pad enables compact PCB layouts with good thermal performance for applications requiring sustained computational load.
When designing with this device, verify supply voltage requirements carefully - the 2.5V variant and 3.3V variant require different DC-DC regulator configurations. Decoupling capacitors should be placed as close as possible to the VDD pins, and the exposed pad must be soldered to a properly sized copper pour for thermal dissipation and electrical grounding.

設計說明
Estimated: The MC9S08GT60CFD core draws approximately 20-30 mA active at 40 MHz with 3.3V supply, based on typical HCS08 family specifications. Decouple VDD pins with 100 nF ceramic capacitors placed within 5 mm of each supply pin, plus a bulk 4.7 uF tantalum or ceramic capacitor near the package. The exposed thermal pad (EP) must be soldered to a ground-connected copper pour of at least 25 mm² to ensure proper thermal dissipation and electrical grounding. Estimated: active power dissipation at full clock is roughly 100 mW; sleep mode reduces this to under 1 mW for battery-friendly operation.
The 48-QFN package requires careful PCB layout: route all signal traces on inner layers if possible to free the top layer for the exposed pad copper pour. Place at least 4 thermal vias (0.3 mm drill, 0.5 mm pad) in the EP copper pour to transfer heat to internal ground planes. Keep high-speed signals (crystal, debug) short and direct. Maintain 50 ohm controlled impedance for external clock traces if used. Allow adequate clearance between analog and digital sections to minimize noise coupling on ADC inputs.
Do not leave the exposed pad (EP) unsoldered - this leads to thermal runaway and unreliable ground reference. Ensure the RESET pin has its internal pullup enabled or an external pullup to VDD; floating reset will cause unpredictable startup behavior. When using BGND debug mode, ensure the BKGD pin is not left floating during normal operation as it can inadvertently enter debug mode. Verify VDD voltage matches the device variant (2.5V or 3.3V) before applying power; overvoltage will damage the device permanently.
