Hi. Phil.
Applied. Thank you.
Best regards, Nobuhiro
2012/5/16 Phil Edworthy phil.edworthy@renesas.com:
This is an sh2a device (max 266MHz) with FPU, video display controller (VDC), 8 serial ports, 4 I2C channels, 3 CAN ports, SD and on-chip USB.
The RSK2+SH7269 board uses the SH7269 processor. It is often referred to as just rsk7269.
