Renesas doubles memory in RX600 series microcontrollers
Renesas Electronics has doubled the on-chip memory in its RX600 microcontrollers for networking equipment applications.
The RX63N/RX631 product groups have up to 256kbyte embedded RAM and 2Mbyte flash.
“The new RX63N/RX631 MCUs with 256kbyte embedded RAM mark the next stage in our on-going miniaturisation process, using our current 90nm enhanced 100MHz zero wait state MONOS process technology,” said Bernd Westhoff, RX Product Manager at Renesas Electronics Europe.
The microcontrollers offer performance of 165 DMIPS (Dhrystone MIPS) at 100MHz CPU and flash operation.
The chips integrate 32kbyte of E2 data flash memory that supports 100,000 rewrite cycles for easy data storage.
There is a new option for 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).
The other features are same as existing RX63N/RX631 groups up to three channels of Controller Area Network (CAN) 2.0B compliant interfaces, two Universal Serial Bus (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 (without 64 and 48-pin packages) also include an EXDMAC unit that can transfer data over an external bus independently of the internal bus occupation.Tags: Renesas
