79RC32T355-150DHGI

The 79RC32T355-150DHGI is a Renesas Interprise™ microprocessor featuring a single MIPS-II 32-bit core running at 150 MHz. Designed for embedded and communications-focused systems, the device integrates memory controllers, high-speed interfaces and on-chip peripherals to support networked and real-time applications in industrial environments.

This industrial‑grade MPU combines processor features such as MMU and caches with a broad set of I/O—10/100 Ethernet, USB 1.1, ATM and TDM support—enabling compact designs that require deterministic control, peripheral integration, and extended temperature operation from -40 °C to 85 °C.

Key Features

• Core  MIPS‑II 32‑bit CPU core at 150 MHz with MMU and EJTAG debug support for development and system control.
• Caches & Memory  On‑chip instruction and data cache architecture (series datasheet details include per‑line cache locking, write‑through/write‑back options) and an SDRAM controller supporting two non‑interleaved banks and a 32‑bit data path.
• DMA & Data Movement  Integrated DMA controller with multiple channels (series documentation notes 16 channels) for memory‑to‑memory and peripheral transfers, supporting descriptor chaining and burst transfers.
• Connectivity  Built‑in 10/100 Mbps Ethernet interface and USB 1.1 full‑speed device controller (series details: USB 1.1, full speed 12 Mb/s, integrated transceiver). Additional ATM and TDM interfaces expand communications flexibility.
• Peripherals & I/O  Rich peripheral set per series documentation: two 16550‑compatible UARTs, flexible I2C, three 32‑bit counter/timers, and up to 36 GPIO pins with programmable functions and interrupt capability.
• System Reliability  On‑chip watchdog and programmable bus transaction timers for system integrity as described in the series documentation.
• Package & Mounting  208‑pin PQFP (28 × 28 mm) surface‑mount package; package case listed as 208‑BFQFP / 208‑PQFP in product data.
• Industrial Qualification & Temperature Range  Industrial qualification with operating temperature range from -40 °C to 85 °C.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Networking & Telecom  Use the integrated 10/100 Ethernet, ATM and TDM interfaces for network access, packet handling and voice/data transport in communications equipment.
• Industrial Control  Industrial‑qualified operation and on‑chip timers, watchdog, and peripheral interfaces make the MPU suitable for embedded controllers and automation systems.
• Embedded Devices with Storage/Memory  On‑chip SDRAM controller and DMA support enable designs that require local memory buffering and fast data movement.
• Peripheral‑Rich Embedded Systems  Multiple UARTs, I2C, GPIO and USB device capability support human‑machine interfaces, sensor aggregation, and peripheral connectivity.

Unique Advantages

• Integrated communications interfaces: On‑chip 10/100 Ethernet, USB 1.1, ATM and TDM reduce external component count and simplify system board design.
• Memory subsystem with SDRAM controller and DMA: Built‑in controllers and DMA channels streamline memory access and high‑throughput transfers without heavy CPU intervention.
• Development and debug support: EJTAG debug interface and MMU support in the MIPS‑II architecture facilitate software development and system bring‑up.
• Industrial temperature operation: Qualified for -40 °C to 85 °C operation, enabling deployment in harsh or temperature‑sensitive environments.
• Compact surface‑mount package: 208‑pin PQFP (28 × 28 mm) package provides a high‑pin‑count solution for complex embedded designs in a single package.
• RoHS compliance: Meets environmental regulations for lead‑free assembly and production.
