描述 Description

The HMS30C7210 is a highly integrated low power microprocessor for card reader system, and other applications described below. The device incorporates an ARM720T CPU and system interface logic to interface with various types of devices. HMS30C7210 is a highly modular design based on the AMBA bus architecture between CPU and internal modules. The on-chip peripherals include LCD controller with DMA support for internal SRAM and external SDRAM memory, analog functions such as ADC and PLL. Intelligent interrupt controller and internal 8 KB SRAM can support an efficient interrupt service execution. The HMS30C7210 also supports a touch panel interface. UART and USB provide serial communication channels for external systems. The power management features result in very low power consumption. The HMS30C7210 provides an excellent solution for card reader system.
