• On-chip Memory — Includes a 2KB instruction cache and a 512B data cache to reduce external memory bandwidth and improve code execution efficiency.
• Integration & System — On-chip multiply/divide unit, instruction and data caches, a 4-deep write buffer and a 4-deep read buffer to minimize memory stalls and simplify system design.
• Bus & I/O Flexibility — Programmable port width support for 8-, 16- and 32-bit memory sub-regions and programmable bus timing controls for flexible interfacing to a range of memory and peripheral devices.
• On-chip Controllers — Integrated DMA arbiter and a 24-bit timer to support data movement and time-based functions without additional external components.
• Clocking — Double-frequency clock input with supported operation at 16.67 MHz, 20 MHz, 25 MHz and 33 MHz, enabling straightforward clocking options for system designs.
• Package & Mounting — 100-TQFP (14 × 14 mm) surface-mount package supplied in tray format for automated assembly.
• Electrical & Environmental — 5 V I/O voltage and commercial operating temperature range of 0 °C to 70 °C; RoHS compliant and consumer-qualified.
• Software & Family Compatibility — Part of the IDT RISController family with pin- and software-compatible devices and available software support such as compilers, RTOS ports and debug monitors.

Typical Applications

• Low-cost Embedded Systems — Suited for compact controllers where integration and reduced external memory needs lower total system cost.
• Consumer Electronics — Useful for consumer device control and user-interface processors that require a 32-bit RISC core and moderate performance at 33 MHz.
• Peripheral Controllers — Acts as a protocol or peripheral controller leveraging on-chip DMA arbitration and timer resources to offload system tasks.
