IDT79R3041-20PF

The IDT79R3041-20PF is a MIPS-I architecture, single-core 32-bit microprocessor module by Renesas, optimized for low-cost embedded applications. It operates at 20 MHz with a 5 V I/O supply and is supplied in a surface-mount 100-TQFP (14×14 mm) package for compact system designs.

Designed with on-chip integration to reduce system BOM and simplify board design, the device includes on-chip instruction and data caches, a multiply/divide unit, programmable bus interface options and on-chip DMA and buffering to support efficient data movement and boot flexibility.

Key Features

• Core & Performance  MIPS-I 32-bit RISC core, single core operating at 20 MHz.
• Instruction and Data Caches  On-chip 2 KB instruction cache and 512 B data cache to reduce external memory bandwidth and improve system performance.
• Bus and Memory Interface  Programmable port width support (8-, 16- and 32-bit memory sub-regions) and programmable bus timing options for flexible memory and peripheral interfacing.
• On-chip Data Path Optimizations  4-deep write buffer and a 4-word read buffer to minimize memory write stalls and support burst or block reads.
• DMA and Timer  On-chip DMA arbiter and a 24-bit timer for streamlined data transfer and timekeeping without external controllers.
• Boot Flexibility  Boot support from 8-, 16- or 32-bit wide PROMs for straightforward firmware storage options.
• Package and Mounting  100-TQFP (14×14 mm) surface-mount package, supplied in tray format for production assembly.
• Electrical and Environmental  5 V I/O voltage and commercial operating temperature range 0 °C to 70 °C; RoHS compliant.
• Qualification  Consumer-qualified device intended for commercial embedded applications.

Typical Applications

• Consumer Electronics  Control and user-interface processing in consumer devices where compact packaging and low system cost matter.
• Embedded Controllers  General-purpose embedded control tasks that benefit from an integrated RISC core, on-chip caches and flexible bus interfacing.
• Instrumentation and Measurement  Data handling and timing tasks using the on-chip DMA and 24-bit timer to reduce external component count.
• Low-cost Network or I/O Appliances  Systems requiring efficient data movement and programmable memory interfacing for varied peripheral widths.

Unique Advantages

• Highly integrated architecture: On-chip caches, multiply/divide unit, DMA arbiter and timers reduce external component count and system complexity.
