Serial ports

Two ports, CMOS-level

UART capabilities

Baudrates of up to 921,600bps; none/even/odd/mark/space parity and 7/8 bits/character

Number of I/O lines

10 general-purpose I/O lines, two of which can serve as interrupts.

GPIO lines 0-7 are combined into port P0, lines 8-9 — into port P1.

Max. load current for each I/O line

12mA for all lines except GPIO1 and GPIO3

1mA for GPIO1 and GPIO3

Pulse-width modulation

PWM output of between 30Hz and 20KHz available on up to nine GPIO lines.

Frequency and duty cycle programming with a 16-bit resolution.

A core clock of 2MHz is used for all lines and is not user-configurable.

Clock frequency

192MHz

Program flash memory

4MB program flash for TiOS and up to two compiled application binaries.

System files use 960KB, TiOS occupies 1,448KB.

The remaining 1,688KB are available for storing user applications.

Flash disk

4MB for hardened, fault-tolerant file system. The entire disk can be used to store application data.

Typical write endurance is 100,000 write cycles per 512-byte sector. For more information, see Flash and EEPROM Memory.

EEPROM memory

2,048 bytes, 2,020 bytes are available for storing application data.

Typical write endurance is about 1,000,000 write cycles per 16-byte EEPROM sector. See Prolonging and Estimating EEPROM life.
