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:.
