16 / 127 page  System description STA108x, STA109x 16/127 DS13319 Rev 2 A specific set of peripherals can be reserved and locked to be only accessible from Cortex-M3, thus allowing a complete independent subsystem to be realized. In addition to that, specific secure GPIOs as well as wake signals are reserved for such subsystem. 2.8 General purpose ADC Accordo2 has a 10-input SAR ADC with 10-bit resolution and sampling frequency up to 2.5 MHz. 2.9 GPIOs Accordo2 has 179 GPIOs in STA109x and 130 in STA108x (16 of which are dedicated to Embedded Isolated Vehicle Interface subsystem). They can be independently configured either as INPUT or OUTPUT. In order to make the system flexible, these IOs are multiplexed on PINs with other peripherals (the alternate function scheme is provided as a separate document). 2.10 Generic interfaces 2.10.1 4x UARTS: Programmable baud rates up to 3 Mbps Hardware Flow control DMA capability. 2.10.2 3x I2C: Master/slave modes in multi-master environment Multiple baud rates supported: 100/400/1000/3400 Kbps DMA capability. 2.10.3 3xSSP/SPI ports supporting: Motorola SPI-compatible interface Texas Instrument synchronous serial interface National Semiconductor Microwire interface Unidirectional interface DMA capability. 2.11 Input capture / Output compare 5 EFT (Enhanced Function timers) implement a very flexible input capture and output compare feature set. Each EFT block can provide 2 Input capture and 2 output PWM lines. EFT are based on 16-bit counters with dedicated prescaler. |
