• Clock and Performance 20 MHz operating frequency (part-specific variant); supports double-frequency clock input and family options for multiple clock rates.
• On-chip Memory Includes a 2 KB instruction cache and a 512 B data cache to reduce external memory bandwidth and improve throughput for embedded code.
• Bus and Interface Programmable bus interface with support for 8-, 16- and 32-bit memory sub-regions and programmable timing controls for flexible system integration.
• On-chip System Features Integrated multiply/divide unit, 24-bit timer, DMA arbiter, 4-deep write buffer and 4-word read buffer to minimize memory stalls and simplify system design.
• Power and I/O 5 V I/O voltage compatible with typical legacy embedded systems.
• Packaging and Mounting 84-pin PLCC (29.31 × 29.31 mm) in tube packaging; surface-mount mounting type for compact board layouts.
• Operating Range and Compliance Commercial temperature qualification (0 °C to 70 °C) and RoHS-compliant construction.

Typical Applications

• Consumer Embedded Devices Microcontroller-class processing for low-cost consumer electronics where integrated system features reduce BOM and simplify firmware development.
• Appliance Control Control and sequencing tasks in household appliances benefiting from on-chip timers, DMA arbitration and compact packaging.
• Human-Machine Interfaces Drive UI control and peripheral management in products requiring a 32-bit RISC core with modest clocking and cache support.
• Cost-Sensitive Industrial Controllers Basic control and monitoring functions in industrial or commercial equipment where commercial temperature range is acceptable.

Unique Advantages

• Highly integrated solution: On-chip caches, arithmetic units, DMA arbiter and timers reduce external components and simplify board-level design.
• Flexible memory interface: Programmable port width and timing controls enable adaptation to 8-, 16- or 32-bit memory devices for design flexibility.
• Reduced memory stalls: On-chip 4-deep write buffer and 4-word read buffer improve effective memory throughput for burst or block reads.
• Proven software ecosystem: Family-level software support (compilers, RTOS, debuggers and emulation libraries) facilitates firmware development and porting.
• Standard packaging and mount: 84-PLCC surface-mount package in tube packaging simplifies procurement and assembly for through-life production.
• RoHS compliant: Meets RoHS requirements for regulatory and environmental compliance in manufacturing.
