Introduction
9/71
High Speed Universal Asynch. Receiver Transmitter (UART)
The three UART interfaces are able to communicate at speeds of up to 2 Mbit/s. They
provide hardware management of the CTS and RTS signals and have LIN Master capability.
To optimize the data transfer between the processor and the peripheral, two FIFOs
(receive/transmit) of 16 bytes each have been implemented.
One UART can be served by the DMA controller (UART0).
Synchronous Serial Peripheral (SSP)
The two SSPs are able to communicate up to 8 Mbit/s (SSP1) or up to 16 Mbit/s (SSP0) in
standard full duplex 4-pin interface mode as a master device or up to 2.66 Mbit/s as a slave
device. To optimize the data transfer between the processor and the peripheral, two FIFOs
(receive/transmit) of 8 x 16 bit words have been implemented. The SSPs support the
Motorola SPI or TI SSI protocols.
One SSP can be served by the DMA controller (SSP0).
Controller Area Network (CAN)
The CAN is compliant with the specification 2.0 part B (active) with a bit rate up to 1Mbit/s. It
can receive and transmit standard frames with 11-bit identifiers as well as extended frames
with 29-bit identifiers. Up to 32 message objects are handled through an internal RAM
buffer. In LQFP64 devices, CAN and USB cannot be connected simultaneously.
Universal Serial Bus (USB)
The STR750F embeds a USB device peripheral compatible with the USB Full speed 12Mbs.
The USB interface implements a full speed (12 Mbit/s) function interface. It has software
configurable endpoint setting and suspend/resume support. The dedicated 48 MHz clock
source is generated from the internal main PLL. VDD must be in the range 3.3V±10% for
USB operation.
ADC (Analog to Digital Converter)
The 10-bit Analog to Digital Converter, converts up to 16 external channels (11 channels in
64-pin devices) in single-shot or scan modes. In scan mode, continuous conversion is
performed on a selected group of analog inputs. The minimum conversion time is 3.75 µs
(including the sampling time).
The ADC can be served by the DMA controller.
An analog watchdog feature allows you to very precisely monitor the converted voltage of up
to four channels. An IRQ is generated when the converted voltage is outside the
programmed thresholds.
The events generated by TIM0, TIM2 and PWM timers can be internally connected to the
ADC start trigger, injection trigger, and DMA trigger respectively, to allow the application to
synchronize A/D conversion and timers.
GPIOs (General Purpose Input/Output)
Each of the 72 GPIO pins (38 GPIOs in 64-pin devices) can be configured by software as
output (push-pull or open-drain), as input (with or without pull-up or pull-down) or as
Peripheral Alternate Function. Port 1.15 is an exception, it can be used as general-purpose
input only or wake-up from STANDBY mode (WKP_STDBY). Most of the GPIO pins are
shared with digital or analog alternate functions.
