PIC32MX150F128B-I/SS Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), working memory (SRAM), and a rich set of peripherals (ADCs, timers, communication interfaces) into one device. Within the broader hierarchy, the PIC32MX1xx family belongs to 32-bit microcontrollers, which sit alongside 8-bit (PIC10/12/16), 16-bit (PIC24, dsPIC33), and 32-bit (Cortex-M) MCU classes, all serving as the central processing unit for embedded systems across consumer, industrial, and automotive markets.
Key features include less than 0.5 mA/MHz active current consumption, two I2S/SPI modules for codec and serial communication, Peripheral Pin Select (PPS) for flexible pin mapping, Parallel Master Port (PMP) for graphics interfaces, mTouch capacitive touch support, 1 ns high-resolution time measurement via the Capture/Compare/PWM peripheral, on-chip temperature measurement, and a Charge Time Measurement Unit (CTMU) for capacitive sensing. The integrated USB 2.0 full-speed Device/Host/OTG controller is a hallmark of the PIC32MX1xx/2xx family.
Architecturally, the MIPS32 M4K core delivers 1.56 DMIPS/MHz and runs at 40 MHz with a zero-wait-state Flash interface. The 5-stage pipeline, hardware multiply/divide, and 32-bit-wide datapath give the PIC32MX150F128B roughly 5x the performance of a comparable PIC24 16-bit MCU. The 10-bit 1 Msps ADC with up to 13 input channels, five 16-bit timers, and two I2C plus two UART interfaces provide extensive analog and digital integration.
Typical applications include USB audio peripherals (headsets, microphones, speakers), capacitive touch human-machine interfaces, industrial control panels with graphics, sensor hub data aggregation, and low-cost 32-bit embedded nodes. The combination of USB, I2S, and PMP makes this device particularly attractive for consumer audio accessories and industrial HMI modules where a single-chip BOM reduces total cost.
Designers should note that achieving 40 MHz operation requires VDD between 2.3V and 3.6V, with careful decoupling of AVDD/AVSS and VDD/VSS pin pairs. The ICSP programming interface uses PGECx/PGEDx pin pairs and requires all VSS and VDD pins to be connected for reliable in-circuit programming and debugging.

Principais diferenciais
- Compact 28-SSOP footprint with full USB 2.0 FS OTG plus 128 KB Flash (vs PIC32MX130F064B-I/SS)
- 40 MHz MIPS32 M4K core at <0.5 mA/MHz active current (vs PIC24FJ64GA002-I/SS)
- On-chip CTMU provides 1 ns time measurement and capacitive touch sensing (vs PIC32MX150F128B-50I/SS)
Notas de projeto
PIC32MX150F128B-I/SS operates from 2.3V to 3.6V with separate analog (AVDD/AVSS) and digital (VDD/VSS) supply pins. Place a 0.1uF ceramic decoupling capacitor as close as possible to each VDD/VSS pin pair, and add a 10uF bulk capacitor near the supply entry point. AVDD must be tied to VDD and AVSS to VSS with its own 0.1uF capacitor. According to the Microchip datasheet, low-ESR ceramic decoupling is essential for stable USB and ADC operation. Estimated: at 40 MHz active the core draws roughly 20 mA from 3.3V, so budget for 30 mA worst-case peak load transients.
USB D+/D- traces require 90 ohm differential impedance matching with continuous ground reference, no splits under the trace, and length matching within 2 mm. The 48 MHz USB clock is generated from the primary oscillator through the PLL, so the crystal placement near OSC1/OSC2 with short traces and a guard ring is critical. According to the Microchip PIC32MX1XX/2XX datasheet, use a parallel-cut crystal with 10-22 pF load capacitors. Estimated: trace length under 25 mm keeps losses acceptable; for longer runs use a twisted pair or shield over a grounded guard trace.
Do not connect only one VDD pin when the device is powered - the PIC32MX150F128B-I/SS has two VDD pins (pin 8 and pin 16) and two VSS pins (pin 5 and pin 15). All supply pins must be connected for proper operation. According to the Microchip datasheet, the ICSP programming interface uses PGECx/PGEDx pin pairs (such as PGEC2/PGED2 on pins 9/10) and all VSS/VDD must be powered for reliable in-circuit programming. Failure to connect all supply pins can cause erratic brown-out resets and Flash programming failures that are difficult to diagnose.
Peripheral Pin Select (PPS) allows remapping of most digital peripheral functions to any remappable I/O pin, but remappable input functions are limited. According to the Microchip PIC32MX1XX/2XX family datasheet, PPS inputs must come from RPBx or RPCx pins, and outputs can be mapped to most I/O pins except VDD/VSS. To minimize EMI, place PPS-reassigned pins adjacent to their peripheral partner and avoid crossing clock or USB signals. Estimated: keeping peripheral trace length under 30 mm reduces signal integrity risks in the 28-SSOP package where routing density is limited.
