VLSI VS23S010C
VS23S010C-L is an easyto-use and versatile serial SRAM device. The memory is accessed via an SPI compatible serial bus. The device also contains Video Display Controller, which can be configured to continuously output analog video from the memory array data to implement a video frame buffer.FEATURES
DESCRIPTION
● Flexible 1.5V - 3.6V operating voltage● 131,072 x 8-bit SRAM organization
● Serial Peripheral Interface (SPI) mode 0 compatible – Byte, Page and Sequential modes – Supports Single, Dual and Quad I/O read and write – Fast operation: the whole memory can be filled in 262158 or read in 262159 cycles (Quad-I/O SPI, Quad address mode) – XHOLD and XWP pins
● 8-bit Parallel Interface (Simplified 8080 and NAND FLASH Type Interface) – Sequential read and write in 4 byte blocks – Fast operation, the whole memory can be filled or read in 131077 cycles
● Integrated Video Display Controller with Video DAC – Supports NTSC and PAL video formats – Fully configurable by user – 9-bit Video DAC and 8x Video PLL
● High operating frequencies – Up to 36 MHz for SPI The VLSI Solution Alternatively, a 8-bit parallel interface can be used to access the SRAM instead of the SPI. To sum up, there are four separate operating modes in VS23S010C-L:
● SPI Single, Dual, or Quad operation and 4 Gene...
