PIC32MM0064GPM028-I/SS Übersicht
A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals on a single silicon die. The PIC32MM GPM family is the lowest-power member of Microchip's PIC32 line, sitting in the hierarchy: 32-bit MCU -> embedded microcontroller -> semiconductor IC. Its microAptiv core supports both MIPS32 and microMIPS instruction sets, the latter compressing common instructions to roughly 30% to save Flash.
Key differentiating features include CoreMark/mA efficiency that allows battery-powered designs to last years, hardware ECC on Flash for IEC 60730 Class B safety compliance, and an integrated USB Full-Speed transceiver that eliminates external components. The 12-bit 200ksps ADC with up to 9 analog inputs and the 5-bit DAC provide mixed-signal capability for sensor conditioning. Six I/O ports supporting peripheral pin select (PPS) give flexible routing for UART, SPI, I2C, and PWM signals.
Architecturally, the device is built on a low-leakage CMOS process with multiple power domains. Deep-sleep currents in the microampere range, configurable idle and sleep modes, and a real-time clock calendar (RTCC) running from a dedicated low-power oscillator enable years of operation from a coin cell. PPS allows remapping of digital peripherals to any I/O, simplifying PCB layout.
Typical applications include IoT sensor nodes, portable medical devices, digital audio accessories, gaming/entertainment peripherals, USB HID devices, low-power wireless sensor hubs, and industrial HMI modules. The 28-SSOP footprint suits hand-solderable prototypes and space-constrained production boards. The device provides 79 CoreMark, ample for BLE/Zigbee host stacks and modest DSP work.
When designing with this MCU, allocate the 16KB RAM carefully - USB stacks and TCP/IP libraries consume significant RAM; budget 4-6KB for the stack and 8-10KB for application data. Use the PPS feature to route peripherals to convenient pins rather than re-spinning the PCB. Enable Flash ECC for safety-critical firmware and use the RTCC with an external 32.768kHz crystal for accurate timekeeping during sleep.

Designhinweise
The PIC32MM0064GPM028-I/SS features multiple low-power modes. For battery-powered designs, use Sleep mode (CPU halted, peripherals running) at about 0.8 mA, Idle mode (CPU halted but peripherals active) for USB polling at about 4 mA active, and Deep Sleep mode (RTCC running, all else off) at under 5 uA. Configure the RTCC to wake the MCU from a 32.768 kHz external crystal for accurate timekeeping during extended sleep. Use PPS to map USB D+/D- lines to the dedicated USB pins and avoid remapping them to maintain USB signal integrity.
Route the USB D+ and D- lines as a 90-ohm differential pair with matched length within 2 mm, keeping them short (under 50 mm total) and isolated from switching signals. Place the VBUS decoupling capacitor (4.7 uF ceramic) within 5 mm of the VBUS pin. Connect both VDD pins (8 and 24) and both VSS pins (7 and 23) to their respective planes with multiple vias for thermal relief. The 28-SSOP is 0.65 mm pitch; use 0.4 mm-wide traces and 0.2 mm spacing on escape routing. Maintain a continuous ground plane beneath the MCU for thermal dissipation and EMI suppression.
Do not exceed 3.6V on any pin; the PIC32MM0064GPM028-I/SS is a 3.3V part and 5V tolerance applies only to specific pins (marked in the datasheet). When using USB bus-powered designs, ensure VBUS never exceeds 3.6V on VDD - add a clamping diode if hot-plug transients are possible. Enable Flash ECC configuration bits in the configuration word for IEC 60730 safety compliance; the ECC bit must be set before Flash writes. PPS must be unlocked before remapping peripherals; failing to unlock causes silent I/O failures.
Place the 32.768 kHz RTCC crystal within 5 mm of the SOSCO/SOSCI pins with short traces and a guard ring tied to analog ground for low-noise timekeeping. Decouple each VDD pin with a 100 nF ceramic capacitor within 2 mm of the pin, plus a 4.7 uF bulk capacitor on each VDD rail. The MCLR pin requires a 10 kohm pull-up to VDD and a 100 nF capacitor to ground for in-circuit debugging; do not omit these or ICSP programming will fail.
The PIC32MM0064GPM028-I/SS in 28-SSOP has a thermal resistance (theta_JA) of approximately 90 C/W on a standard 4-layer JEDEC test board. At maximum active current of 15 mA at 3.3V, dissipation is about 50 mW, resulting in a junction temperature rise of only 4.5 C above ambient - well within safe limits. In Deep Sleep mode, dissipation drops to about 15 uW. No heatsink is required. For industrial -40C to +85C environments, ensure ambient temperature plus self-heating stays below 125 C junction.
