suspend/resume. The USB OTG full-speed controller requires a dedicated 48 MHz clock

that is generated by a PLL connected to the HSE oscillator. The major features are:

●

Combined Rx and Tx FIFO size of 1024× 35 bits with dynamic FIFO sizing

●

Supports the session request protocol (SRP) and host negotiation protocol (HNP)

●

6 bidirectional endpoints

●

12 host channels with periodic OUT support

●

Internal FS OTG PHY support

●

External FS OTG PHY support through an I2C connection

●

External HS or HS OTG operation supporting ULPI in SDR mode. The OTG PHY is

connected to the microcontroller ULPI port through 12 signals. It can be clocked using

the 60 MHz output.

●

Internal USB DMA

●

HNP/SNP/IP inside (no need for any external resistor)

●

For OTG/Host modes, a power switch is needed in case bus-powered devices are

connected

2.2.35

Audio PLL (PLLI2S)

The devices feature an additional dedicated PLL for audio I2S application. It allows to

achieve error-free I2S sampling clock accuracy without compromising on the CPU

performance, while using USB peripherals.

The PLLI2S configuration can be modified to manage an I2S sample rate change without

disabling the main PLL (PLL) used for CPU, USB and Ethernet interfaces.

The audio PLL can be programmed with very low error to obtain sampling rates ranging

from 8 kHz to 192 kHz.

In addition to the audio PLL, a master clock input pin can be used to synchronize the I2S

flow with an external PLL (or Codec output).

2.2.36

Digital camera interface (DCMI)

The camera interface is not available in STM32F205xx devices.

STM32F207xx products embed a camera interface that can connect with camera modules

and CMOS sensors through an 8-bit to 14-bit parallel interface, to receive video data. The

camera interface can sustain up to 27 Mbyte/s at 27 MHz or 48 Mbyte/s at 48 MHz. It

features:

●

Programmable polarity for the input pixel clock and synchronization signals

●

Parallel data communication can be 8-, 10-, 12- or 14-bit

●

Supports 8-bit progressive video monochrome or raw Bayer format, YCbCr 4:2:2

progressive video, RGB 565 progressive video or compressed data (like JPEG)

●

Supports continuous mode or snapshot (a single frame) mode

●

Capability to automatically crop the image

2.2.37

GPIOs (general-purpose inputs/outputs)

Each of the GPIO pins can be configured by software as output (push-pull or open-drain,

with or without pull-up or pull-down), as input (floating, with or without pull-up or pull-down)

or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog
