Renesas ups microcontroller RAM

4 September 2013 DSP, Micros & Memory

Renesas Electronics announced the expansion of its 32-bit RX microcontroller (MCU) platform. It is introducing 120 new models, expanding the successful RX631 and RX63N product groups within the RX600 series of 32-bit MCUs.

These new RX63N/RX631 groups, for use in network equipment, offer up to 256 KB embedded RAM, doubling the previously available memory size of 128 KB. These new products are pin-to-pin compatible with existing models, and therefore recommended as a drop-in replacement for customers with larger RAM requirements.

The new MCUs achieve high performance of 165 DMIPS at 100 MHz CPU and Flash operation. They offer a wide and scalable product extension from 1 MB to 2 MB Flash integration by keeping 256 KB RAM for all of these product variations. In addition, all these products integrate 32 KB of E2 data Flash memory that supports 100 000 rewrite cycles for easy data storage.

The package type is LQFP, allowing Renesas to provide products appropriate for a wide variety of embedded equipment supporting 100 to 176 pins.

As a new feature, the new RX63N/RX631 models integrate an optional Data Encryption Unit (DEU) which enables customers to use encryption/decryption functions according to the AES standard. The encryption engine supports AES (128-, 192- and 256-bit key length).

Other features are the same as existing RX63N/RX631 members: up to three channels of Controller Area Network (CAN) 2.0B com­pliant interfaces, two USB full speed hosts, USB OTG and device features and an Ethernet MAC IEEE 802.3 interface, compliant with Media Independent Interface (MII) and Reduced Media Independent Interface (RMII), for easy connection to a PHY (RX63N only).

The RX63N/RX631 groups of MCUs (excluding 64- and 48-pin packages) also include an EXDMAC unit that can transfer data over an external bus independently of the internal bus occupation. This allows these MCUs to easily support TFT solutions for up to QVGA or WQVGA class TFT panels, even if there is no dedicated LCD controller used in the application.

These new devices include a real-time clock (RTC) that reduces power consumption by offering 2 V operation. The RTC module includes an anti-tamper detection function that independently detects system state changes with three pins while the CPU is in the power off state and not operating. It also assigns timestamps.
