xcore^®.ai for I/O

Flexible I/O
Configurability

xcore.ai processors provide flexibility in I/O pin mapping, enabling:

• Up to 128 flexible I/O ports that support bi‑directional and strobed operation on data widths of 1 to 32 bits.
• I/O configured by firmware to support evolving system and protocol requirements without hardware change.
• Operation at both 1V8 and 3V3 logic levels supported to simplify interfacing to external devices.

Real-Time
Responsiveness

• Programmable state machines in the I/O ports which can buffer and serialise data.
• Processing cores can be dedicated to specific I/O events, ensuring hard real‑time event processing providing predictable latency for I/O operations.
• Event driven scheduling model ensures that compute resources are guaranteed to be available.

Extensive
Peripheral Support

• Connect with a wide range of peripherals through xcore.ai processors.
• A large library of software defined peripherals covers many standard interface types; TDM,PCM or PDM data, I2S or S/P DIF, audio, I2C, UART, MIDI etc.
• Dedicated USB, MIPI and LLDDR PHYs built in for high performance, optimising both system performance and cost.

Precise
Timing Control

• I/O ports provide nanosecond level precision for applications your applications with xcore.ai’s advanced timing control capabilities.
• The processors feature programmable timers and clocking mechanisms, ensuring accurate synchronisation and coordination of I/O operations.
