VS23S010C-S Datasheet PRELIMINARY VS23S010C-S - 1 Megabit SPI SRAM with Dual-I/O and Quad-I/O Features 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) XCS SO/IO1 XWP/IO2 GND 1 2 3 4 8 VCC 7 XHOLD/IO3 6 SCLK 5 SI/IO1 Figure 1: SOIC8 narrow package, compatible with standard pin out (not to scale). Operating Modes – XHOLD and XWP pins High operating frequencies – Up to 36 MHz for SPI Active Low-power – Read current 200 µA at 1 MHz (Single I/O, SO=0, TA=+85◦C, VDD=3.3V) Industrial temperature range – -40◦C to + 85◦C Pb-Free and RoHS compliant 1,048,576 bit (128K x 8) SRAM Array Description The VLSI Solution VS23S010C-S is an easyto-use and versatile serial SRAM device. The memory is accessed via an SPI compatible serial bus. Applications Microcontroller RAM extension VoIP and internet data stream buffer Audio data buffer SPI Serial Interface Figure 2: VS23S010C-S blocks In SPI mode SRAM and control registers can be accessed. Dual-I/O and Quad-I/O modes are used only for SRAM read and write. Following are connection examples for different operating modes. Some I/Os of VS23S010CS are unconnected, because they have internal pull-up or pull-down resistors. Note also, Version:...
