PIC32MX534F064LT-I/PT - 80MHz 32-bit MCU 64KB Flash | Microchip

The Microchip Technology PIC32MX534F064LT-I/PT is a 32-bit MIPS32 M4K microcontroller operating up to 80 MHz, integrating 64 KB of flash program memory and 16 KB of SRAM in a 100-pin TQFP (12x12x1 mm) package. The part ships in tape-and-reel (T) packaging and is rated for the industrial -40C to +85C temperature range (I-grade). It includes integrated USB 2.0 full-speed and CAN 2.0b peripherals, four DMA channels, and the standard PIC32MX5xx analog/mixed-signal feature set. A 32-bit microcontroller (MCU) is a programmable processor core that executes instructions from on-chip flash memory, integrates RAM and a broad set of peripherals (USB, CAN, timers, ADC, I/O), and forms the central controller in an embedded system. Within the PIC32MX family, the MX5xx sub-family is positioned above the MX1/MX2 value line and below the MX6/MX7 high-performance line, targeting USB- and CAN-equipped industrial, medical, and consumer applications that benefit from MIPS M4K processing throughput. Key features of this part include the 80 MHz MIPS32 M4K core with 5-stage pipeline, hardware multiply/divide, single-cycle multiplication, prefetch cache, and 64 KB flash that supports live updates through the ICSP interface. The 16 KB SRAM allows reasonable data buffering without external memory, while the four DMA channels offload data movement from the CPU. The USB 2.0 full-speed on-chip transceiver and the CAN 2.0b controller reduce external component count. The 100-pin TQFP package exposes up to 85 general-purpose I/O pins and supports parallel master port (PMP) operation for external bus expansion. Typical applications include industrial USB-to-CAN bridges, HMI panels with USB device connectivity, embedded dataloggers, medical instrument controllers, and general-purpose 32-bit nodes in factory automation networks. The combination of USB device, CAN, and ample I/O makes this MCU a strong fit for industrial nodes that must communicate with both a host PC and a CAN fieldbus. Designers should plan for a 3.3V core supply with typical 2.0V-3.6V operating range, place a 10 uF plus 0.1 uF decoupling network near each power pin pair, and follow Microchip's USB hardware design guidelines (impedance-controlled 90 ohm differential routing, common-mode choke) when the USB peripheral is enabled. The 'T' suffix indicates tape-and-reel, so pick-and-place programming and full production-line rework should follow standard JEDEC MSL-3 handling.

The DMA controller supports up to 8 independent channels and triggers on peripheral events, allowing continuous USB or ADC operation without CPU intervention. The USB OTG module includes the physical layer, requiring only an external pull-up or pull-down resistor on the D+/D- lines and a few decoupling components for a compliant USB port. The part fits inside industrial control panels, USB peripherals, point-of-sale terminals, sensor hubs, medical data loggers, and consumer audio accessories. The compact 121-ball TFBGA package suits space-constrained PCB layouts such as wearable dongles and portable test instruments where a QFP would be too tall or too large. Designers select the PIC32MX534 family when balancing USB integration, deterministic interrupt latency, and Microchip's MPLAB Harmony firmware ecosystem against the lower cost of 8-bit PIC16/PIC18 parts. When designing with this device, plan for decoupling (100 nF + 1 uF near each VDD pair), keep the USB trace length under 50 mm with 90-ohm differential impedance, and configure the oscillator PLL that enables ripple-free USB clocks without overshoot. The MPLAB Harmony configurator and the PICkit 5 in-circuit debugger are the recommended toolchain for production programming and firmware development, providing validated peripheral drivers and a USB stack. This page synthesizes distributor pricing for the PIC32MX534F064LT-V/BG, drop-in alternatives within the same 121-ball TFBGA footprint, and practical layout and USB design notes that the manufacturer datasheet does not present in a single reference.

The Industrial (-I) suffix specifies an operating temperature range of -40C to +85C, while the -50 suffix confirms the 50 MHz top speed grade. The PIC32MX5XX family bridges mainstream 8/16-bit PIC designs to full 32-bit processing with Peripheral Pin Select (PPS) remapping for flexible board layouts. A 32-bit microcontroller is a programmable system-on-chip that integrates a CPU core, volatile and non-volatile memory, and a rich set of peripherals (timers, ADC, communication interfaces) on a single silicon die. The PIC32MX family is a key node in Microchip's product taxonomy: it sits above the 16-bit PIC24/dsPIC families and below the Cortex-M class SAM and PIC32MK parts. Designers choose PIC32MX when they want Microchip's MPLAB X toolchain maturity and PPS flexibility without paying for the higher-pin-count or higher-speed PIC32MZ/MK families.

Charge Time Measurement Unit (CTMU) provides capacitive touch and basic analog front-end functions, while PPS remaps most digital peripherals to any compatible I/O pin. The architecture uses a 5-stage MIPS M4K pipeline with hardware multiply/divide and a tightly coupled prefetch cache that mitigates Flash wait states at 50 MHz. The 3.3V core supply with internal regulators lets the device run directly from a 2.3V to 3.6V rail, simplifying power tree design. On-chip debug over JTAG or 2-wire programming via ICSP is supported throughout the family. Typical applications include USB peripherals and HID devices, CAN-connected industrial nodes with DeviceNet, HMI/graphic display controllers via PMP, audio streaming with I2S codecs, capacitive touch user interfaces using CTMU, and low-cost connectivity bridges for sensors. The combination of USB, CAN, and PMP also fits automotive telematics, building automation controllers, and point-of-sale terminals. A key design consideration: at 50 MHz the Flash access wait states must be configured via the system registers, and PMP timing for graphics requires careful setup of the data setup and hold registers - consult the family reference manual section on PMP for your chosen panel. Vcap pin must be left unloaded except for the required 10 uF decoupling.

It integrates USB 2.0 full-speed, CAN 2.0B, two I2S audio interfaces, four SPI modules, two I2C modules, and a Parallel Master Port (PMP) with dual read/write buffers aimed at graphics and HMI applications. Two on-chip analog comparators and a 16-channel 1 MSPS 10-bit ADC round out the analog subsystem. 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 on one die. The PIC32MX5xx family sits in the hierarchy MIPS32 -> M4K core -> PIC32 -> 32-bit microcontroller -> embedded MCU, designed to balance deterministic real-time control with the throughput required by audio decoding, USB stacks, and small graphical displays. Key features include 256 KB Flash (256K x 8), 32 KB SRAM, Peripheral Pin Select (PPS) for flexible I/O mapping, an RTCC with calendar mode, a Charge Time Measurement Unit (CTMU) for capacitive touch sensing, and a wide operating voltage of 2.5 V to 3.6 V. Industrial temperature range is -40C to +85C, matching the I/PT suffix. The architecture combines a Harvard-style M4K core with a 5-stage pipeline and hardware multiply/divide, plus a dedicated DMA controller and a 16-channel hardware crypto-free RTCC. PPS remaps most digital peripherals to nearly any I/O pin, which simplifies PCB routing when migrating between PIC32MX5xx variants and speeds up BOM consolidation. Typical applications include USB audio peripherals, CAN-connected industrial nodes, low-cost HMI panels with PMP-driven TFT displays, capacitive touch user interfaces using CTMU, and small embedded graphics controllers. The combination of two I2S ports and USB makes the part a natural fit for USB-DAC dongles and USB-to-S/PDIF bridges. When designing with this device, allocate at least 4.7 uF bulk + 0.1 uF bypass capacitors on VDD/AVDD and provide a 32.768 kHz crystal or external reference for the RTCC. Pay attention to PPS remapping in code: each peripheral function must be unlocked in the device configuration to be assigned to a physical pin.

Key features include 64 KB (64K x 8) Flash program memory, 32 KB SRAM, 80 MHz maximum CPU clock, USB On-The-Go (OTG) full-speed and low-speed transceiver, a 10-bit 1 Msps ADC with up to 16 channels, DMA with multiple channels for offloading CPU transfers, and configurable I/O. The 64-VQFN (9x9 mm) package offers a low-profile surface-mount footprint suitable for compact embedded designs. Architecturally, the PIC32MX564 uses the MIPS32 M4K core with 5-stage pipeline, Harvard cache, and a peripheral bus that connects USB, ADC, SPI, I2C, UART, and CAN modules to the DMA engine. This architecture delivers deterministic interrupt latency and 1.56 DMIPS/MHz, which is sufficient for USB stack processing, motor control loops, and basic signal processing without external logic. Typical applications include USB peripherals (HID, CDC, MSD), industrial control with CAN, embedded graphics controllers, low-cost sensor hubs, and consumer devices that need on-board USB connectivity. The integrated USB OTG PHY eliminates an external transceiver and reduces BOM cost. When designing with this device, allocate sufficient decoupling on VDD/VSS pairs (typically 100 nF per pin) and keep the 80 MHz trace lengths short to avoid EMI. The 64-VQFN package exposes a thermal pad that must be soldered to a continuous ground plane for thermal dissipation and electrical reference.

Internal phase-locked loop multiplies the external oscillator up to 80 MHz for high throughput while supporting low-power clock domains. The MIPS M4K core executes most instructions in a single cycle and includes a hardware multiplier, single-precision FPU-less DSP extensions and a 16-bit instruction set mode for code density. The unified 4 GB linear address space simplifies memory mapping, and 4-channel DMA offloads peripheral and memory-to-memory transfers, freeing the CPU for control-plane tasks. Brown-out reset, watchdog timer and configurable interrupt controller support IEC 60730-class safety routines. Typical applications include USB peripherals and HID devices, industrial control and HMI, sensor and instrumentation data loggers, low-cost graphics terminals using PMP-driven LCDs, medical point-of-care devices, and CAN/USB gateway nodes. The PIC32MX564F064H-V/PT is qualified for industrial temperature ranges, making it well suited to factory automation, building control and outdoor telemetry. When designing with this part, ensure the 3.3 V supply is well decoupled with 100 nF and 10 uF bulk capacitors placed within 5 mm of each VDD/VSS pair. Configure the PLL loop filter components per datasheet recommendations and reserve the RTCC pins if a 32.768 kHz crystal is used for the real-time clock. Always program the Configuration Words and oscillator startup delays before exiting the reset vector to avoid USB enumeration failures.

PIC32MX564F064HT-V/MR

PIC32MX564F064HT-V/MR - 80MHz 32-bit MCU 64KB Flash | Microchip

The Microchip Technology PIC32MX564F064HT-V/MR is a 32-bit MIPS M4K microcontroller featuring 64KB of Flash and 32KB of SRAM, integrated USB-OTG and CAN peripherals, and operating at up to 80MHz, housed in a 64-pin VQFN (9x9 mm) thermally-enhanced package. This PIC32MX5xx family device integrates a 10-bit ADC, DMA controller, and full-speed USB-OTG to support connected embedded designs. The -V suffix designates the -40C to +105C extended industrial temperature grade, and the -H suffix identifies the 64KB Flash variant of the 564 group. What is a PIC32MX microcontroller? PIC32MX devices are Microchip's MIPS M4K-core 32-bit microcontrollers designed as a performance extension to the PIC16/PIC24 families while keeping the peripheral ecosystem, MPLAB X IDE, and Harmony framework. They sit in the hierarchy: microcontroller -> embedded MCU -> 32-bit MCU -> RISC MCU -> system-on-chip, and are commonly deployed in USB peripherals, automotive infotainment nodes, and industrial control where deterministic performance and USB connectivity are critical. Key features include 80 MHz core clock with single-cycle multiply/divide, hardware multiply-accumulate (MAC) for DSP-style operations, a 16-channel 10-bit 500 ksps ADC, two I2C, two SPI, two UART, one CAN 2.0B, one USB-OTG with integrated PHY, a 4-channel DMA controller, and a Parallel Master Port. Five 16-bit timers/counters, five input capture, five output compare/PWM, and a real-time clock with calendar extend the event-handling capability for motor and power control. Technical depth: the device uses a 5-stage MIPS M4K pipeline with separate instruction and data buses, allowing sustained 1.25 DMIPS/MHz (Dhrystone 2.1). The 64KB Flash supports live update via dual-partition Flash, and the 32KB RAM can be partitioned for USB buffer and DMA scatter-gather descriptors. Internal regulators derive 1.8V core from a 2.3V to 3.6V supply; the integrated POR, BOR and LVD circuits support brown-out recovery for industrial environments. Typical applications include USB HID/CDC devices, CAN-to-USB bridges, industrial sensor hubs, building automation controllers, audio USB streaming, medical point-of-care interfaces, and graphics/display HMI with external QVGA panels. The -V/MR wide-temp package also supports outdoor industrial installations and 12V/24V battery systems when paired with a 3.3V LDO. Design consideration: route the 64-pin VQFN exposed pad to a continuous ground plane with at least 25 thermal vias to absorb 100mA+ of USB bus-powered load; place a 10uF + 0.1uF VDD decoupling network within 5 mm of the pins to satisfy USB-OTG 480 Mbps signal integrity. For CAN-bus designs, use an isolation-capable 3.3V transceiver such as MCP2551 to support 1 Mbps CAN-HS.
