Would it be possible to interface the BF592 to an SRAM via PPI to serve as a frame buffer. The system description consistes of: Analog sensor -> AD7944 A/D (2 MSPS @14 bit) -> processor via SPI. The goal is to capture 2 MBytes of data from the sensor in real time; buffer the data and then transmit the captured data via RF transmitter to external receiver. Need small, low power, inexpensive solution. The BF592 would be ideal if the frame buffer could be easily implemented.
