EFM32PG1B200F256GM48-C0 概要
An ARM Cortex-M4 microcontroller is a 32-bit processor core based on the ARMv7-M architecture, featuring Thumb-2 instruction set, hardware single-cycle multiply, optional single-precision IEEE 754 floating-point unit, and a tightly coupled Nested Vectored Interrupt Controller (NVIC). Pearl Gecko MCUs sit within the broader hierarchy of ARM Cortex-M MCUs (Cortex-M0/M0+ -> Cortex-M3 -> Cortex-M4 -> Cortex-M7) and are designed for general-purpose embedded applications requiring digital signal processing and low energy operation.
Key specifications include an operating voltage range of 1.85 V to 3.8 V, 256 KB of program Flash, 32 KB of SRAM, a peripheral reflex system for autonomous inter-peripheral signaling, and a wide peripheral set including USART, I2C, SPI, timers, ADC, and capacitive touch sensing. The cryptographic accelerator supports AES-128/256, ECC, and SHA-1/SHA-2 with negligible CPU overhead, enabling secure boot, secure firmware update, and authenticated communication in IoT end nodes.
Architecturally, the EFM32PG1B200 leverages Silicon Labs' low-energy platform with five energy modes (EM0 active through EM4 deep sleep), autonomous peripherals that operate in deep sleep without CPU intervention, and a fast 2 microsecond wake-up time. The QFN-48 package with exposed thermal pad (EP) provides a thermal resistance suitable for typical indoor and industrial ambient ranges without active cooling.
Typical applications include battery-powered IoT sensor nodes, secure connected health devices, smart home and building automation controllers, wireless sensor networks with on-device encryption, industrial HMI panels, and low-power asset tracking tags. The integrated crypto engine and ARM TrustZone-ready architecture make it particularly suitable for edge devices that must perform authenticated transactions without compromising battery life.
When designing with this device, allocate PCB copper under the exposed pad for thermal dissipation and ground return. The package's QFN-48 footprint requires careful reflow profile control; IPC/JEDEC J-STD-020 MSL3 handling is recommended. Decoupling requires 100 nF on each VDD pin plus a bulk 4.7 uF, and a 32.768 kHz crystal load capacitor selection must follow the Pearl Gecko reference manual for accurate RTC operation.

設計ノート
The 48-QFN package has an exposed thermal/ground pad on the underside (pin 49). This pad MUST be soldered to a ground plane on the PCB for proper electrical performance and thermal dissipation. The datasheet recommends an array of thermal vias (typically 9-16 vias on 0.5 mm pitch) under the EP to provide a low-impedance thermal path to internal ground layers. IPC-2221 land pattern guidelines apply; reflow profile should follow JEDEC J-STD-020 MSL3 handling for moisture-sensitive components.
Place decoupling capacitors as close as possible to each VDD pin. Silicon Labs recommends 100 nF X7R ceramic on each VDD pin plus a bulk 4.7 uF or 10 uF tantalum/ceramic capacitor on the main supply rail. Separate analog and digital ground planes should join at a single point near the MCU's exposed pad. Estimated: at 40 MHz active mode, peak current draw is approximately 11 mA per the EFM32PG1 datasheet; design the LDO or switching regulator for at least 50 mA headroom for peripheral inrush.
Do not confuse the EFM32PG1B200F256GM48-C0 (256 KB Flash) with the EFM32PG1B200F128GM48 (128 KB Flash) - both share the same QFN-48 footprint but firmware designed for 256 KB will not fit in 128 KB. Verify the exact memory size in the device marking before PCB assembly. Also note that the C0 suffix indicates ordering code variant (tray packaging by default); for high-volume SMD assembly, use the -C0R tape-and-reel variant to match pick-and-place feeders.
The EFM32PG1B200F256GM48-C0 typically dissipates under 50 mW in active mode at 40 MHz and under 10 microW in EM4 deep sleep. Standard temperature grade (G suffix) operates from -40C to +85C; for industrial applications requiring +125C, select the IM48 industrial-grade variant. At maximum active current of approximately 11 mA at 3.8 V, junction temperature rise is negligible given the QFN-48 EP's thermal resistance of approximately 30 C/W. Provide adequate PCB copper pour under the exposed pad for reliable thermal performance.
