PIC32MX150F128B-V/SS Visão geral
A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a CPU core, Flash program memory, SRAM, and a rich set of peripherals on a single die. Within the broader taxonomy, PIC32MX devices sit in the microcontroller -> embedded controller -> semiconductor hierarchy. The MIPS M4K core supports the MIPS32 instruction architecture, providing 32-bit datapath performance while remaining code-compatible with the broader PIC32 ecosystem. This PIC32MX150/170/1XX family targets cost-sensitive embedded designs needing USB, audio, and graphics interfaces.
Key features include two I2S/SPI modules for codec and serial communications, Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) for graphics interfaces, and support for mTouch capacitive touch buttons and sliders. The integrated Charge Time Measurement Unit (CTMU) provides 1 ns high-resolution time measurement, while an on-chip temperature sensor simplifies thermal monitoring without external components. Five general-purpose 16-bit timers and a 10-bit ADC round out the analog and timing peripherals.
Architecturally, the M4K core is a 5-stage pipeline RISC processor with hardware multiply/divide, delivering 1.56 DMIPS/MHz. The 128 KB Flash is organized as 128K x 8 with ECC support, and 32 KB SRAM provides ample workspace for protocol stacks and audio buffers. PPS is particularly valuable because it allows digital peripheral pins to be remapped in software, simplifying PCB layout when signals would otherwise need to cross.
Typical applications include USB audio peripherals, low-cost graphics HMI with PMP-driven LCDs, capacitive touch key panels, industrial control with mTouch, and automotive body controllers benefiting from the extended -40°C to +105°C grade. The device is well-suited to bridge products transitioning from PIC16/PIC24 designs to 32-bit performance.
When using this part, ensure the 32 kHz crystal and PLL configuration follow the datasheet's oscillator tuning procedure to meet USB Full-Speed timing. JTAG/ICSP pads must remain accessible for in-circuit programming if the application does not dedicate them to other functions.

Principais diferenciais
- Highest temperature grade in the 150F128B family (vs PIC32MX150F128B-I/SS)
- Standard 40 MHz core speed (vs PIC32MX150F128B-50I/SS)
- Same die as industrial variant for supply flexibility (vs PIC32MX150F128B-I/SP)
Notas de projeto
The PIC32MX150F128B-V/SS has two VDD/VSS pairs (pins 7/8 and 18/19) plus additional VSS pins 13. Decouple both VDD pairs with 100 nF ceramic capacitors placed as close to the respective pins as possible, with a bulk 10 µF tantalum or aluminum-polymer capacitor nearby on the supply rail. For USB applications, route the D+ and D- traces with 90 Ω differential impedance and add ferrite beads if the design has noisy switching nodes near the USB connector. Brown-out reset (BOR) should be enabled during the LDO module configuration.
The 28-pin SSOP package has 0.65 mm pitch which is hand-solderable but tight for rework; reserve at least 8 mil traces and 8 mil spacing on PCB escape routing around the device. Use a 4-layer PCB with a continuous ground plane beneath the device for best EMI and signal integrity. The ICSP/PGED1/PGEC1 pins (pins 9 and 10) must remain accessible to a programming header or test pad - do not dedicate them to other peripherals if field updates are required. JTAG pins 25-28 are alternate functions and can be released to general I/O via the JTAGEN bit in CFGCON after programming.
Do not confuse the -V/SS suffix with the -V/SO or other package codes - the -SS denotes SSOP only. When migrating firmware between the -V/SS and -50I/SS variants, the clock configuration bits and peripheral library headers must be updated, although user code is otherwise source-compatible. Watch for PPS remap conflicts: when the USB D+/D- pins (20, 21) are used in PPS mode they cannot simultaneously act as GPIO RB8/RB9, so plan pin allocation before code freeze. PPS input pin groups are limited and the datasheet pin selection tables (section 11.0 I/O Ports) must be consulted to ensure a signal can be mapped to the desired physical pin.
Estimated: At maximum 40 MHz active current of <0.5 mA/MHz, the MCU core draws roughly 20 mA. Combined with I/O pin currents (sourced up to 15 mA per pin in groups), worst-case device power dissipation at 3.6 V is approximately 75 mW, well below SSOP-28 thermal limits. In typical USB audio applications running at 30% duty cycle, total power is around 30 mW, allowing PCB-only thermal management. No external heatsink is required for normal operation, but the device should be derated to 70 mA total I/O current per the absolute maximum ratings.
