The 73S1215F-44IM/F is an 80515 system on chip in 44 pin QFN package. This versatile and economical CMOS device is intended for smart card reader applications. The circuit features an ISO 7816/EMV interface, an USB 2.0 interface (full speed 12Mbps device) and 5x6 PINpad interface. Maximum design flexibility is supported with additional features such as 9 user I/Os, multiple interrupt options, up to 4 programmable current outputs and 1 analogue voltage input. A built-in hardware interfaces include an asynchronous serial UART and an I2C interface. The system on chip is built around an 80515 high performance core. Its feature and instruction set is compatible with industry standard 8051 while offering one clock cycle per instruction processing power (most instructions) with CPU clock running up to 24MHz. The circuit requires a single crystal which frequency can be between 6MHz and 12MHz.
