PIC32MX330F064H-I/MR - 100MHz 32-bit MIPS MCU, 64KB Flash | Microchip

The Microchip Technology PIC32MX330F064H-I/MR is a 32-bit MIPS32 M4K RISC microcontroller running up to 100 MHz (50 MHz in this -I speed grade) with 64 KB Flash and 16 KB SRAM, packaged in a 64-pin 9x9 mm VQFN with exposed thermal pad. It targets cost-sensitive embedded applications that need USB-OTG, audio/I2S, and analog peripherals in a small footprint. The PIC32MX3/4 family integrates two I2S channels, USB-OTG, a 10-bit 1 Msps ADC, and a charge time measurement unit (CTMU) for capacitive touch sensing. What is a PIC32MX microcontroller? The PIC32MX family is Microchip's MIPS32-based 32-bit MCU line, bridging the 8-bit PIC16/PIC18 world and the higher-end Cortex-M platforms. These 32-bit microcontrollers sit in the power-management and signal-processing tier, sitting above 8-bit microcontrollers and below Cortex-M4 MPUs, within each category in the broader semiconductor hierarchy. Designers choose PIC32MX for deterministic interrupt latency, mature MPLAB Harmony support, and rich connectivity including I2C, SPI, UART, PMP, IrDA, and LIN. Key features of this part include 64 KB Flash program memory, 16 KB SRAM, 53 digital I/O lines, 5 16-bit timers/counters, two I2S/SPI channels, USB-OTG full-speed, a 10-bit 1 Msps ADC with up to 28 analog inputs, and a CTMU for capacitive touch. The 64-VQFN (9x9) package exposes a thermal pad, lowering theta-JA to roughly 22 C/W on a 4-layer JEDEC PCB. Operating voltage is 2.3 V to 3.6 V and the temperature grade is -40 C to +85 C industrial. Architecturally, the device uses the MIPS32 M4K core with single-cycle hardware multiply and divide, a 5-stage pipeline, and tightly coupled peripherals through a peripheral bus matrix. The 16 KB of data RAM is split into two banks to feed the 8-channel DMA engine, which off-loads SPI, I2S, UART, and ADC transfers. The USB-OTG controller is integrated on-chip with internal transceiver, requiring only external ESD protection and the 5 V VBUS supply path. Typical applications include USB audio peripherals, low-cost HMI touch panels, motor control signal conditioning, industrial sensor nodes, and consumer appliances that need USB device functionality. Designers also use this part in dataloggers, USB-to-UART bridges, and battery-powered instrumentation thanks to multiple low-power sleep modes down to sub-mA standby. When designing with this MCU, ensure the exposed pad (EP) is soldered to a sufficiently large copper pour (at least 1 sq inch) for thermal relief. Decouple VDD with 0.1 uF ceramic plus 4.7 uF bulk within 5 mm of the pins, and isolate the analog AVDD with a ferrite bead plus 10 nF + 1 uF capacitor network to keep ADC noise below 1 LSB.

The Microchip PIC32MX340F128HT-80V/PT is a 32-bit MIPS M4K microcontroller operating at up to 80 MHz (80 MIPS), integrating 128 KB of Flash program memory and 32 KB of SRAM, and packaged in a 64-pin TQFP (10x10x1 mm). It is part of the PIC32MX3xx/4xx family that targets cost-effective 32-bit migration paths for designs previously implemented on PIC24/dsPIC. A 32-bit microcontroller (MCU) is an integrated microprocessor core plus RAM, non-volatile program memory, and a rich set of peripherals on a single die. The PIC32MX family is built around the MIPS32 M4K core, which executes the MIPS32 Release 2 instruction set with hardware multiply/divide and a 5-stage pipeline, giving MCU-class parts true 32-bit ALU, pointer, and register width at clock rates competitive with mid-range ARM Cortex-M3 devices. PIC32MX devices occupy the bridge between 8/16-bit MCU families and high-performance Cortex-M parts.

PIC32MX340F128L-80I/BG - 32-bit 80MHz MCU, 128KB Flash, 121-TFBGA

The Microchip Technology PIC32MX340F128L-80I/BG is a 32-bit MIPS microcontroller from the PIC32MX3XX/4XX family, featuring an 80 MHz MIPS32 M4K core, 128 KB of Flash program memory, and 32 KB of SRAM, packaged in a 121-ball TFBGA (10x10 mm). It integrates a 10-bit ADC, USB 2.0 full-speed On-The-Go, CAN 2.0b, and a wide range of peripherals designed for connected embedded applications. A 32-bit microcontroller (MCU) is an integrated circuit that combines a high-performance processor core, program memory, data memory, and a rich peripheral set on a single die. PIC32MX MCUs leverage the MIPS32 instruction set with 5-stage pipeline and hardware multiply/divide, positioning them in the same performance tier as early ARM Cortex-M3 devices while offering Microchip's MPLAB development ecosystem. The 80 MHz core delivers 105 DMIPS, giving PIC32MX340F128L more than 2x the throughput of 16-bit PIC24/dsPIC parts at similar clock rates. Key features of this part include 53 general-purpose I/O pins, 5 16-bit timers/counters, 2 I2C, 2 UART, 2 SPI, 2 CAN, 1 USB OTG, 1 PMP/PSP, and a 16-channel 10-bit ADC with 1 Msps conversion rate. The device operates from 2.5V to 3.6V, supports industrial -40C to +85C temperature range (I-grade), and provides two 32-bit shadow register sets for fast context switching in RTOS environments. Architecturally, the PIC32MX340F128L uses a Harvard bus architecture with separate instruction and data paths, MIPS16e code compression for up to 40% smaller program footprint, and a peripheral bus that offloads DMA from the core. The on-chip DMA controller supports 8 channels and can move data between peripherals and RAM without CPU intervention - critical for streaming USB, CAN, and ADC data. Typical applications include industrial control with CAN networking, USB-based data acquisition modules, medical instrumentation requiring 32-bit math, and embedded HMI with PMP-driven LCD. The integrated USB OTG makes it well suited for point-of-sale terminals and portable diagnostic tools that need to enumerate as USB device or host. When designing with this device, plan a 3.3V LDO supply with bulk + bypass capacitance near each VDD/VSS pair. The 121-ball TFBGA requires 4-layer PCB with microvia or via-in-pad for reliable manufacturing; budget for X-ray inspection on production boards. Configure the on-chip LPRC/FRC oscillators and use the PLL only when peripheral timing jitter is critical.

The "-80V" suffix indicates the 80 MHz speed grade and the V-temp extended operating range of -40C to +105C; the "-80I" counterpart operates -40C to +85C. A 32-bit microcontroller (MCU) is an integrated circuit containing a 32-bit CPU core, on-chip program and data memory, and programmable peripherals, executing instructions from a Harvard-architecture core where program and data buses are separated. 32-bit MCUs sit at the top of the MCU taxonomy: MCU > 32-bit MCU > MIPS/ARM/Cortex > RISC > embedded processor, and they deliver higher code density, faster arithmetic, and more deterministic interrupt latency than 8-bit or 16-bit MCUs. The PIC32 family extends Microchip's legacy PIC instruction set into 32-bit performance while preserving the MPLAB development ecosystem. The PIC32MX340F128L-80V/PT integrates a single-cycle 32x32 hardware multiply/divide unit, supports MIPS16e code compression for up to 40% smaller code size, and provides a 5-stage pipeline that can sustain 105 DMIPS at 80 MHz. On-chip DMA channels offload peripheral transactions from the CPU, and the peripheral pin select (PPS) system remaps digital functions to user-selected I/O pins, simplifying PCB routing. A 16-bit timer/capture/PWM module and an RTCC (Real-Time Clock Calendar) support motor control and timekeeping without external components. Typical applications include USB peripherals (HID, CDC, MSD class devices), industrial control panels, motor control boards, human-machine interfaces (HMIs) with color TFT displays, point-of-sale terminals, and consumer audio products. The 53 I/O pins and 100-pin package make it well suited to mid-complexity designs that exceed the I/O budget of smaller PIC32 parts, while the 128 KB Flash accommodates full USB stacks and graphical user interface libraries. When designing with this MCU, allocate the high-frequency oscillator pins (OSC1/OSC2) close to the IC with a guard ring, keep the Vcap/Vddcore power trace short, and follow the PIC32MX3XX/4XX Family Silicon Errata sheet for any device revision-specific behaviors. Use MPLAB Harmony or MPLAB XC32 to maximize code density via MIPS16e, and validate USB signal integrity with the on-chip 48 MHz PLL configured per the USB clock tree requirements in the datasheet.
