LONDON, UK – 1st February - Renesas Technology Europe announced today
the immediate availability of the SH7721 microprocessor for battery-operated
devices that use TFT displays and feature-rich Linux user interfaces.
The SH7721 SH-3-based microprocessor has 170 DMIPS performance, 32Kbyte
unified cache and a five-stage pipeline. It integrates a TFT-controller with up
to 1024x1024 resolution, depending on colour depth, and with an associated
dedicated 2.4Kbyte line-buffer RAM to prevent flickering. Further support for
state-of-the-art user interfaces includes an Analog-to-Digital-Converter (ADC)
that can be used for touch-screen control. The device also features USB
host/function and many serial ports including two UARTS with 128 Byte FIFO,
IIC, Multi-media card-Interface (MMC), Smartcard-Interface, IrDA and
others.
The peripheral set is completed by many timers including a Real-Time-Clock
(RTC) and a PCMCIA 2.1 – compliant PC-Card Controller (PCC) to enable easy
extension of the system using readily available PCMCIA cards. Finally a
flexible Bus-State-Controller (BSC) enables direct connection to Flash, RAM and
SDRAM. A six-channel DMA offloads the CPU from data movements.
To facilitate long battery live or USB-powered operation, the SH7721 only
consumes 600mW when everything is in full operation and at full speed. The
power consumption can be further reduced using clock gearing and low-power
modes such as sleep and standby. For example, in standby mode and with the RTC
maintained, the device consumes only 50μA (max).
The SH7721 is now available in two RoHS compliant 256-pin BGA package. The
packages measure only 11x11mm for extremely compact telecoms applications, or
17x17mm for less space-constraint consumer/industrial applications.
The device is supported by a reference platform (MS7721RP01), which is
available ex stock and supported by Renesas Technology’s popular
E10A debugger (HS0005KCU01H without trace, HS0005KCU02H with trace).
C-Compiler options are the Renesas C Compiler as well as the free-of-charge
GNU C Compiler from KPIT (www.gnush.com).
The linux BSP can be downloaded at www.superh-linux.org and www.shlinux.com.
System integrator services are available from Renesas Technology Europe’s
certified alliance partners such as emtrion (www.emtrion.com), MPC-Data (www.mpc-data.co.uk) and many others (
