Key Features

• Core & Architecture MIPS‑I single‑core, 32‑bit processor running at 33 MHz, delivering deterministic integer processing for embedded workloads.
• On‑chip Memory Includes a 2 KB instruction cache and a 512 B data cache to reduce external memory bandwidth and improve code/data locality.
• Bus & Memory Interface Programmable bus interface with support for 8‑, 16‑ and 32‑bit memory sub‑regions and programmable timing (extended address hold, bus turn around, read/write masks) for flexible system memory configurations.
• System Integration On‑chip multiply/divide unit, 4‑deep write buffer, 4‑word read buffer, DMA arbiter and a 24‑bit timer reduce external logic and simplify system design.
• Clocking & Performance Options Double‑frequency clock input and support for multi‑rate operation; this part is specified for 33 MHz operation.
• Package & Mounting Supplied in a 100‑TQFP (14×14) surface‑mount package, delivered in Tape & Reel (TR) format for automated assembly.
• Electrical & Environmental 5 V I/O voltage and commercial operating temperature range of 0 °C to 70 °C. RoHS compliant.
• Software & Ecosystem Part of a family with complete software support including optimizing compilers, real‑time operating systems, monitors/debuggers and floating point emulation software.

Typical Applications

• Low‑cost embedded controllers — Compact single‑chip processing for cost‑sensitive systems where integrated peripherals and caches reduce BOM and board area.
• Consumer electronics — Commercial temperature range and RoHS compliance suit a variety of consumer applications requiring reliable control and interface processing.
• Peripheral and I/O controllers — Programmable bus timing, port width support and on‑chip DMA simplify interfacing to external memory and peripherals.
• Embedded control systems — On‑chip timer, buffering and arithmetic units support control loops, peripheral management and general application tasks.

Unique Advantages

• Highly integrated solution: On‑chip CPU, caches, DMA arbiter, timers and buffer structures reduce the need for external components and lower system cost.
• Flexible memory interface: Programmable port width (8/16/32‑bit) and timing controls enable straightforward interfacing to a wide range of memory and peripheral devices.
• On‑chip buffering and DMA: 4‑deep write buffer, 4‑word read buffer and DMA arbitration minimize memory stalls and simplify burst/block transfers.
• Compact, production‑friendly packaging: 100‑TQFP (14×14) in Tape & Reel supports automated assembly while preserving PCB real estate.
• Commercial readiness: 0 °C to 70 °C operating range, 5 V I/O and RoHS compliance make the device suitable for mainstream consumer and embedded products.
• Software ecosystem: Family‑level software support (compilers, RTOS, debug tools, emulation) helps accelerate development and integration.
