System

Multilayer AHB matrix interconnect provides a separate bus for each AHB master. AHB masters include the CPU, and General Purpose DMA controller. This interconnect provides communication with no arbitration delays unless two masters attempt to access the same slave at the same time.
Split APB bus allows for higher throughput with fewer stalls between the CPU and DMA. A single level of write buffering allows the CPU to continue without waiting for completion of APB writes if the APB was not already busy.
Embedded Trace Macrocell (ETM) module supports real-time trace.
Boundary scan for simplified board testing.

Memory

512 kB on-chip flash program memory with In-System Programming (ISP) and In-Application Programming (IAP) capabilities. The combination of an enhanced flash memory accelerator and location of the flash memory on the CPU local code/data bus provides high code performance from flash.
Up to 96 kB on-chip SRAM includes: 64 kB of main SRAM on the CPU with local code/data bus for high-performance CPU access. Two 16 kB peripheral SRAM blocks with separate access paths for higher throughput. These SRAM blocks may be used for DMA memory as well as for general purpose instruction and data storage.
Up to 4032 byte on-chip EEPROM.

LCD controller, supporting both Super-Twisted Nematic (STN) and Thin-Film Transistors (TFT) displays

Dedicated DMA controller.
Selectable display resolution (up to 1024 x 768 pixels).
Supports up to 24-bit true-color mode.

Serial interfaces

Quad SPI Flash Interface (SPIFI) with four lanes and up to 40 MB per second.
Ethernet MAC with MII/RMII interface and associated DMA controller. These functions reside on an independent AHB.
USB 2.0 full-speed dual port device/host/OTG controller with on-chip PHY and associated DMA controller.
Five UARTs with fractional baud rate generation, internal FIFO, DMA support, and RS-485/EIA-485 support. One UART (UART1) has full modem control I/O, and one UART (USART4) supports IrDA, synchronous mode, and a smart card mode conforming to ISO7816-3.
Three SSP controllers with FIFO and multi-protocol capabilities. The SSP interfaces can be used with the GPDMA controller.
Three enhanced I²C-bus interfaces, one with a true open-drain output supporting the full I²C-bus specification and Fast-mode Plus with data rates of 1 Mbit/s, two with standard port pins. Enhancements include multiple address recognition and monitor mode.
I²S (Inter-IC Sound) interface for digital audio input or output. It can be used with the GPDMA.

Digital peripherals

SD/MMC memory card interface.
Up to 165 General Purpose I/O (GPIO) pins depending on the packaging, with configurable pull-up/down resistors, open-drain mode, and repeater mode. All GPIOs are located on an AHB bus for fast access and support Cortex-M4 bit-banding. GPIOs can be accessed by the General Purpose DMA Controller. Any pin of ports 0 and 2 can be used to generate an interrupt.
Two external interrupt inputs configurable as edge/level sensitive. All pins on port 0 and port 2 can be used as edge sensitive interrupt sources.
Four general purpose timers/counters, with a total of eight capture inputs and ten compare outputs. Each timer block has an external count input. Specific timer events can be selected to generate DMA requests.
Quadrature encoder interface that can monitor one external quadrature encoder.
Two standard PWM/timer blocks with external count input option.
One motor control PWM with support for three-phase motor control.
Real-Time Clock (RTC) with a separate power domain. The RTC is clocked by a dedicated RTC oscillator. The RTC block includes 20 bytes of battery-powered backup registers, allowing system status to be stored when the rest of the chip is powered off. Battery power can be supplied from a standard 3 V lithium button cell. The RTC will continue working when the battery voltage drops to as low as 2.1 V. An RTC interrupt can wake up the CPU from any reduced power mode.
Event Recorder that can capture the clock value when an event occurs on any of three inputs. The event identification and the time it occurred are stored in registers. The Event Recorder is located in the RTC power domain and can therefore operate as long as there is RTC power.
Windowed Watchdog Timer (WWDT). Windowed operation, dedicated internal oscillator, watchdog warning interrupt, and safety features.
CRC Engine block can calculate a CRC on supplied data using one of three standard polynomials. The CRC engine can be used in conjunction with the DMA controller to generate a CRC without CPU involvement in the data transfer.

Analog peripherals

Two analog comparators.

Power control

Four reduced power modes: Sleep, Deep-sleep, Power-down, and Deep power-down.
The Wake-up Interrupt Controller (WIC) allows the CPU to automatically wake up from any priority interrupt that can occur while the clocks are stopped in Deep-sleep, Power-down, and Deep power-down modes.
Processor wake-up from Power-down mode via any interrupt able to operate during Power-down mode (includes external interrupts, RTC interrupt, PORT0/2 pin interrupt, and NMI).
Brownout detect with separate threshold for interrupt and forced reset.
On-chip Power-On Reset (POR).

Clock generation

On-chip crystal oscillator with an operating range of 1 MHz to 25 MHz.
12 MHz Internal RC oscillator (IRC) trimmed to 1% accuracy that can optionally be used as a system clock.
An on-chip PLL allows CPU operation up to the maximum CPU rate without the need for a high-frequency crystal. May be run from the main oscillator or the internal RC oscillator.
A second, dedicated PLL may be used for USB interface in order to allow added flexibility for the Main PLL settings.
