PIC32MX320F128H-80V/MR - 32-bit MCU 128KB Flash 80MHz | Microchip

The Microchip Technology PIC32MX320F128H-80V/MR is a 32-bit MIPS M4K microcontroller running at 80 MHz with 128 KB of Flash program memory and 16 KB of SRAM, housed in a 64-pin VQFN (9x9 mm) package with exposed thermal pad. It is part of the PIC32MX3xx/4xx general-purpose and USB family and provides 53 general-purpose I/O pins, a 10-bit 1 Msps ADC with up to 16 channels, USB 2.0 full-speed OTG, and four 16-bit timers plus two 32-bit timers. What is a PIC32MX microcontroller? The PIC32MX is Microchip's 32-bit MIPS-based MCU family that bridges the gap between 8/16-bit PIC microcontrollers and 32-bit ARM Cortex-M parts. PIC32MX devices use the MIPS32 M4K core, which combines deterministic interrupt response with higher performance than legacy PIC24/dsPIC DSC devices, while remaining pin-compatible with many PIC24/dsPIC packages. The hierarchy is: microcontroller -> 32-bit MCU -> PIC32 family -> PIC32MX sub-family -> general purpose / USB series. Key features include hardware multiplier/divider for DSP-class math, two I2C, two SPI, and two UART modules, five 16-bit capture inputs and five 16-bit compare/PWM outputs, a 10-bit ADC and a 10-bit analog comparator, Fail-Safe Clock Monitor (FSCM), configurable Watchdog Timer with on-chip low-power RC oscillator, and multiple power-management modes (Run, Idle, Sleep). The VQFN-64 package offers a compact 9x9 mm footprint suitable for space-constrained industrial and consumer designs. Architecturally, the M4K core executes most instructions in a single cycle and includes a hardware multiply/divide unit and a 5-stage pipeline, giving the PIC32MX320F128H class-leading code density for 32-bit performance at near 8-bit cost. Peripherals connect to the core through a separate peripheral bus, simplifying register mapping and allowing deterministic DMA-driven data movement for USB and ADC. Typical applications include USB peripherals, industrial control panels, HMI touch interfaces, consumer audio devices, sensor hubs, and low-cost graphics terminals. The wide operating range and integrated USB 2.0 full-speed make it a frequent choice for upgrading legacy PIC24 designs without changing PCB layout. When designing with this MCU, ensure the VQFN exposed pad is soldered to a sufficiently large ground copper pour to meet thermal and electrical requirements; inadequate thermal pad soldering is the most common cause of PIC32MX VQFN reliability issues. Configure the FSOSC and FNOSC configuration bits carefully and use the Fail-Safe Clock Monitor if the application must tolerate crystal start-up failure.

A 32-bit microcontroller (MCU) is a single-chip computer that integrates a high-performance processor core, Flash program memory, SRAM data memory, and a rich set of on-chip peripherals (ADC, timers, USB, UART, SPI, I2C). PIC32MX parts use the MIPS M4K core, placing them in the broader hierarchy MCU -> microcontroller -> embedded processor -> semiconductor, and they are widely deployed when 8/16-bit parts lack the throughput or memory needed for graphical user interfaces, USB stacks, or real-time control loops. Key features of this part include 128 KB on-chip Flash organized as 128K x 8, 16 KB SRAM, an 80 MHz maximum CPU clock (40 MHz system clock for peripherals), five 16-bit timers/counters, two I2C, two SPI, two UART channels, USB 2.0 full-speed device/host/OTG, a 16-channel 10-bit ADC with 1 Msps, and a parallel master port. The industrial temperature grade (-40C to +85C) and 2.3V-3.6V single supply operation simplify integration into harsh environments. The architecture combines a 5-stage pipelined MIPS32 core with single-cycle multiplication and hardware divide, enabling 1.56 DMIPS/MHz and excellent deterministic interrupt response. The PMD (peripheral module disable) and power-saving modes let idle peripherals draw near-zero current, which is critical for USB bus-powered and battery-backed designs. Typical applications include USB human-interface devices, industrial control and HMI panels, embedded web servers, data loggers, sensor hubs, and low-cost graphics terminals. The 80 MHz performance, USB, and 128 KB Flash cover most mid-range connected-embedded workloads. When designing with this MCU, budget for a 2.3V-3.6V LDO and follow Microchip's recommended decoupling network (100 nF + 10 uF bulk). Always program the device through the ICSP interface using MPLAB X IDE + XC32 compiler; never assume 80 MHz operation without proper PLL configuration.

It integrates 128 KB (128K x 8) of Flash program memory alongside 32 KB of data RAM, and the -80I speed grade with industrial -40C to +85C temperature range supports robust operation across embedded environments. A 32-bit microcontroller (MCU) is a programmable processor core, memory, and peripheral set integrated into a single silicon die. Within the broader semiconductor hierarchy, MCUs sit under microprocessors (MP/MPU) but add on-chip Flash, RAM, timers, ADCs, and communication interfaces, making them self-contained compute subsystems. PIC32MX devices extend Microchip's legacy PIC16/PIC24 family into the MIPS32 domain, enabling 80 MHz performance with familiar MPLAB X toolchain support. Key features of the PIC32MX320F128L include a 16-channel 10-bit Analog-to-Digital Converter (ADC) for mixed-signal acquisition, four DMA channels that offload CPU cycles during peripheral data transfers, and a rich set of serial interfaces: multiple UART/EUSART, I2C, and SPI ports. The device also provides five 16-bit timers/counters, configurable I/O, and a USB 2.0 full-speed On-The-Go peripheral on select die revisions, enabling direct USB device/host bridging without an external PHY. Architecturally, the PIC32MX320F128L uses a Harvard-style 32-bit MIPS core with separate instruction and data buses feeding Flash and SRAM, providing deterministic interrupt latency and predictable execution. A peripheral bus matrix multiplexes ADC, I/O, and serial blocks, while a bus master DMA engine can move data between peripherals and RAM independently of the CPU. The 121-ball TFBGA exposes the full pinout, including extended I/O and parallel bus options that the smaller 64/100-pin variants omit. Typical applications include USB peripherals such as HID-class input devices and CDC serial bridges, industrial sensor hubs that aggregate multiple analog and digital channels via DMA, graphical user interfaces with parallel bus displays, and embedded connectivity nodes combining UART, SPI, and I2C peripherals. The wide combination of FFT-friendly MIPS performance and abundant peripherals makes it a fit for low-cost audio processing, motor-control feedback loops, and protocol bridges. When laying out a board, allocate a 10x10 mm BGA land pattern with 0.8 mm pitch fan-out and route differential USB DP/DM pairs with 90 ohm impedance matching. Decouple each VDD/AVDD pin with a 100 nF ceramic capacitor placed within 2 mm of the ball, and add a 4.7 uF bulk capacitor near the regulator output. The 'I' suffix denotes industrial temperature range, while the trailing 'BG' designates the 121-ball TFBGA package, distinguishing it from pin-compatible QFP variants in the same die family.

The device operates from 2.3 V to 3.6 V and is rated -40 C to +105 C for industrial environments. The PIC32MX320 architecture uses a 5-stage pipeline M4K core with hardware multiply/divide and a single-cycle Flash prefetch module that lets the CPU execute from Flash with near-RAM throughput. Peripheral DMA moves ADC, UART and SPI traffic independently of the core, freeing MIPS for application code and improving real-time determinism in control loops. Typical applications include USB peripherals and HID devices, industrial HMI panels, motor control front-ends, data loggers, and consumer audio/video accessories that need a USB-OTG-capable 32-bit controller with low BOM cost. The 121-ball TFBGA package targets space-constrained designs where board area is at a premium but routing density is high. When designing with this part, allocate decoupling caps near every VDD/VSS pin pair and follow the recommended 80 MHz crystal or external clock layout guidelines; the parallel master port pins are multiplexed with I/O and must be tri-stated in software when used as general-purpose I/O to avoid contention. Engineers should also verify that supply ramp meets the 0.1 ms minimum spec to avoid POR issues.

PIC32MX330F064LT-V/TL - 80MHz 32-bit MCU 64KB Flash | Microchip
PIC32MX330F064LT-V/TL

PIC32MX330F064LT-V/TL - 80MHz 32-bit MCU 64KB Flash | Microchip

The Microchip Technology PIC32MX330F064LT-V/TL is a 32-bit MIPS32 M4K microcontroller operating at 80 MHz with 64 KB of Flash program memory and 16 KB of SRAM, housed in a 124-pin VTLA (9x9 mm) surface-mount package. The device integrates two I2S/SPI interfaces, an 8-bit PMP for graphics or external memory, a 10-bit 1 Msps ADC, USB-OTG, DMA, and standard serial connectivity (UART, I2C, IrDA, LINbus). What is a 32-bit microcontroller? A microcontroller is a compact integrated circuit containing a processor core, program memory (Flash), working memory (RAM), and a rich set of on-chip peripherals such as ADC, communication controllers, and timers. PIC32MX devices specifically use the MIPS32 M4K Harvard architecture, which separates instruction and data buses to allow simultaneous fetch and memory access. The PIC32MX3/4 family sits within the broader taxonomy of 32-bit microcontrollers (PIC32 -> MIPS32 M4K -> MCU -> embedded processor -> semiconductor), providing significantly more performance than 8/16-bit MCUs while retaining the PIC ecosystem's peripheral integration. Key differentiating features include 64 KB (64K x 8) Flash and 16 KB RAM, a 10-bit 1 Msps ADC, two I2S/SPI modules for audio codec interfacing, USB-OTG full-speed support, DMA for offloading CPU data movement, and an on-chip 8-bit Parallel Master Port (PMP) for graphics or external memory expansion. The 'V' temperature grade targets -40C to +105C operation for industrial and automotive under-hood environments, while 'L' denotes the 64-pin-compatible low-pin-count family variant. The PIC32MX330F064L silicon uses a 5-stage pipeline MIPS32 M4K core with hardware multiply/divide and a zero-overhead hardware loop counter. Code execution from Flash uses a prefetch cache to mask Flash wait-states, sustaining close to 80 MHz throughput across most C code. The integrated DMA controller can service peripherals and memory-to-memory transfers autonomously, freeing the core for application logic. Typical applications include industrial control interfaces with USB-OTG device or host connectivity, low-cost graphical HMI panels using the PMP bus, audio codec front-ends with I2S, sensor aggregation nodes with UART/I2C peripherals, and USB peripherals such as HID-class instruments. The wide -40C to +105C operating range also makes it suitable for outdoor industrial equipment. Design tip: VTLA-124 is a thermally-enhanced thin-array land-grid package that requires careful PCB land pattern and via-in-pad design for reliable reflow and thermal dissipation; refer to Microchip's package specification for recommended pad and stencil dimensions. Decoupling must include a 0.1 uF ceramic per VDD/VSS pair plus a bulk capacitor close to the regulator.

The Microchip PIC32MX340F128H-80I/PT is a 32-bit MIPS M4K microcontroller with 128KB Flash, 32KB RAM, and USB 2.0 full-speed support, packaged in a 64-pin TQFP (10x10 mm) and operating at up to 80MHz (105 DMIPS). It integrates a 5-stage pipelined MIPS core with MIPS16e code compression, hardware multiply/divide, and 32x32-bit core registers for fast context switching and deterministic interrupt response. What is a PIC32MX microcontroller? The PIC32MX series is Microchip's family of 32-bit microcontrollers based on the MIPS M4K core, designed as a natural migration path from 8-bit PIC16/PIC18 and 16-bit PIC24/dsPIC devices. PIC32MX sits in the broader hierarchy: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS-based MCU -> USB-capable MCU -> Microchip PIC32MX family. This category is widely used for low-power, USB-enabled, and general-purpose embedded designs that need more memory and processing headroom than 8/16-bit MCUs while staying within cost-constrained budgets. Key features of the PIC32MX340F128H-80I/PT include: 80MHz/105 DMIPS performance, 128KB Flash program memory, 32KB SRAM, 53 digital I/O pins, a 10-bit 1 Msps ADC with up to 16 channels, USB 2.0 full-speed device/host/OTG, two I2C, two UART, and two SPI peripherals, plus five 16-bit timers/captures. The industrial-grade -40C to +85C operating range and 2.3V-3.6V supply make it suitable for harsh embedded environments. Architecturally, the device uses a Harvard bus configuration with separate 32-bit instruction and data paths, a prefetch cache to mitigate Flash wait states, and a programmable vector interrupt controller. Compared to ARM Cortex-M0/M3 contemporaries, the PIC32MX340 offers a competitive DMIPS/mW ratio for general-purpose control with the added benefit of Microchip's mature MPLAB XC32 toolchain, Harmony framework, and PICkit-5 in-circuit debugger support. Typical applications include USB peripherals (HID, CDC, mass storage), industrial control panels, building automation, sensor hubs, home appliances, motor-control BLDC/PMSM companion processors, and consumer audio docks. The integrated USB OTG enables dongle-free device-to-device communication, while the 10-bit ADC with 16 channels supports multi-sensor acquisition. Designers should note that the -80I/PT suffix indicates the 80MHz industrial-temperature variant in TQFP packaging. Pin-compatible PIC32MX3xx/4xx family members with different Flash/RAM densities (32KB, 64KB, 256KB) provide scalable migration paths within the same PCB footprint. Always provide bulk decoupling near each VDD/VSS pair and follow Microchip's recommended USB PCB layout for the D+/D- lines.
