Description:
RP2040 IC Microcontroller to the physical world by allowing it to speak to almost any external device. High-performance breezes through integer workloads. Low cost helps ease the barrier to entry.
Raspberry PI RP2040 IC Microcontroller Chip is designed to help you bring every last drop of that power to bear. With six independent banks of RAM, and a fully connected switch at the heart of its bus fabric, you can easily arrange for the cores and DMA engines to run in parallel without contention.
RP2040 Chip builds Raspberry Pi’s commitment to inexpensive, efficient computing into a small and powerful 7 mm × 7 mm package, with just two square millimetres of 40 nm silicon.
Features:
- Dual ARM Cortex-M0+ @ 133MHz
- 264kB on-chip SRAM in six independent banks
- Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
- DMA controller
- Fully-connected AHB crossbar
- Interpolator and integer divider peripherals
- On-chip programmable LDO to generate core voltage
- 2 on-chip PLLs to generate USB and core clocks
- 30 GPIO pins, 4 of which can be used as analogue inputs
- Peripherals
- 2 UARTs
- 2 SPI controllers
- 2 I2C controllers
- 16 PWM channels
- USB 1.1 controller and PHY, with host and device support
- 8 PIO state machines
Pin Description:
- Number of processor cores (2)
- Loosely which type of processor (M0+)
- floor(log2(RAM / 16k))
- floor(log2(nonvolatile / 16k)) or 0 if no onboard nonvolatile storage
- GPIOx: General-purpose digital input and output. RP2040 can connect one of a number of internal peripherals to each GPIO, or control GPIOs directly from software.
- GPIOx/ADCy: General-purpose digital input and output, with analogue-to-digital converter function. The RP2040 ADC has an analogue multiplexer which can select any one of these pins, and sample the voltage.
- QSPIx: Interface to a SPI, Dual-SPI or Quad-SPI flash device, with execute-in-place support. These pins can also be used as software-controlled GPIOs, if they are not required for flash access.
- USB_DM and USB_DP: USB controller, supporting Full Speed device and Full/Low Speed host. A 27Ω series termination resistor is required on each pin, but bus pull-ups and pull-downs are provided internally.
- XIN and XOUT: Connect a crystal to RP2040’s crystal oscillator. XIN can also be used as a single-ended CMOS clock input, with XOUT disconnected. The USB bootloader requires a 12MHz crystal or 12MHz clock input. For recommended crystals, see Crystal Oscillator.
- RUN: Global asynchronous reset pin. Reset when driven low, run when driven high. If no external reset is required, this pin can be tied directly to IOVDD.
- SWCLK and SWDIO: Access to the internal Serial Wire Debug multi-drop bus. Provides debug access to both processors, and can be used to download code.
- TESTEN: Factory test mode pin. Tie to GND
- GND: GND Single external ground connection, bonded to a number of internal ground pads on the RP2040 die.
- IOVDD: Power supply for digital GPIOs, nominal voltage 1.8V to 3.3V
- USB_VDD: Power supply for internal USB Full Speed PHY, nominal voltage 3.3V.
- ADC_AVDD: Power supply for analogue-to-digital converter, nominal voltage 3.3V.
- VREG_VIN: Power input for the internal core voltage regulator, nominal voltage 1.8V to 3.3V.
- VREG_VOUT: Power output for the internal core voltage regulator, nominal voltage 1.1V, 100mA max current.
- DVDD: Digital core power supply, nominal voltage 1.1V. Can be connected to VREG_VOUT, or to some other board-level power supply.
