Product details
Overview
MA320001 from Microchip Technology is a 32-bit PIC32MX general-purpose microcontroller featuring the MIPS32 M4K core, 80 MHz operation, 128 KB Flash + 12 KB boot Flash, 16 KB SRAM, and USB 2.0 full-speed OTG support. It integrates five 16-bit timers, 16-channel 10-bit ADC (1000 ksps), two I²C modules, two UARTs with IrDA support, and hardware DMA-targeted for embedded control in industrial HMI and USB-connected sensor gateways.
For engineers reviewing the MA320001 datasheet, MA320001 pinout, MA320001 application, or MA320001 equivalent, this page delivers verified package mapping (100-pin TQFP), confirmed peripheral register atomicity, USB-dedicated DMA channel allocation, VREG-enabled self-powered USB mode, and real-time trace capability-key selection criteria for deterministic real-time firmware development and USB device certification.
Technical Context
The MA320001 implements a 5-stage pipelined MIPS32 M4K CPU core with prefetch cache and MIPS16e code compression, enabling 1.56 DMIPS/MHz performance at zero-wait-state Flash access. It uses separate PLLs for CPU and USB clock domains, supporting independent 80 MHz CPU operation and 48 MHz USB clock generation from a 3–25 MHz crystal.
Its peripheral set includes atomic SET/CLEAR/INVERT operations on select registers for race-free bit manipulation, four-channel programmable DMA with automatic data size detection, and dual UARTs supporting RS-232/RS-485/LIN protocols plus on-chip IrDA encoder/decoder-enabling robust multi-protocol serial communication without software overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIC32MX440F128L | USB OTG with dedicated DMA; same 100-pin TQFP package; adds VBUS sensing and USBID pin | Required for host-mode USB or VBUS-aware self-powered designs | Select when USB host capability or dynamic VBUS detection is needed |
| STM32F407VGT6 | ARM Cortex-M4F core; 168 MHz; 1 MB Flash; no integrated USB PHY regulator (requires external VBUS sensing) | Higher performance for DSP-intensive tasks; lacks native VREG for USB self-power | Choose for floating-point math or Ethernet needs; verify external USB power architecture |
Compared with PIC32MX440F128L, MA320001 omits USBID and VBUSON pins-making it suitable only for fixed-role USB device operation. Versus STM32F407VGT6, MA320001 provides integrated VREG and simpler USB power management but lower clock speed and Flash capacity.

FAQ
What is the maximum operating frequency of the MA320001 microcontroller?
The MA320001 operates at a maximum frequency of 80 MHz, achieved via its internal PLL locked to an external 3–25 MHz crystal or oscillator. This frequency enables 1.56 DMIPS/MHz performance using the MIPS32 M4K core, supporting real-time deterministic execution for industrial control loops and USB transaction scheduling without CPU bottlenecks.
Does the MA320001 support USB device mode without external regulators?
Yes, the MA320001 includes an integrated VREG regulator that supplies 3.3V to the USB PHY, enabling true self-powered USB device operation directly from the USB VBUS line. No external LDO is required-simplifying design and reducing BOM cost-provided the application draws less than the 100 mA VREG current limit specified in DS61143H.
How many analog input channels does the MA320001 ADC support, and what is its conversion rate?
The MA320001 features a 16-channel, 10-bit successive-approximation ADC capable of 1000 ksps (kilo-samples per second) maximum conversion rate. All channels support simultaneous sampling during Sleep or Idle modes, allowing continuous background acquisition without CPU intervention-ideal for sensor fusion in battery-operated edge nodes.
What debug interfaces are available on the MA320001?
The MA320001 provides two hardware debug interfaces: a 2-wire interface supporting unintrusive real-time data exchange during application execution, and a 4-wire MIPS-standard enhanced JTAG interface compliant with IEEE 1149.2 for boundary scan and full-featured emulation. Both are accessible via standard PICkit or REAL ICE tools in the MPLAB ecosystem.
Is the MA320001 pin-compatible with other PIC32MX devices?
Yes, the MA320001 (PIC32MX320F128L) shares identical pinout and electrical characteristics with other 100-pin TQFP variants in the PIC32MX3XX family-including PIC32MX340F128L and PIC32MX360F256L-enabling drop-in replacement for increased Flash/SRAM without PCB redesign, provided peripheral configuration matches the target variant's feature set.
