Description

The GMS30C7201 is a highly-integrated microprocessor for personal digital assistants, and other applications described below. The device incorporates an ARM720T CPU, Piccolo DSP, and system interface logic to interface with various types of devices. GMS30C7201 is a highlymodular design based on the AMBA bus architecture between CPU and internal modules.

The on-chip peripherals include keyboard controller, VGA and LCD controller complete with DMA support for external SDRAM memory. The GMS30C7201 also supports voice recording, sound playback and a touch panel interface. Piccolo enables softmodems to be used, and an on chip CODEC interface enables a low-cost modem solution.

The power management features of GMS30C7201 result in very low power consumption.

The GMS30C7201 provides an excellent solution for personal digital assistants(PDAs) ,and data terminal running the Microsoft Windows CE operating system. Other applications include smart phones, Internet appliances, car navigation, particularly where Windows CE support is required.
