VS23S010C-L - 1 Megabit SPI SRAM
with Serial and Parallel Interfaces
and Integrated Video Display Controller
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 mem-
ory 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 cy-
cles
Integrated Video Display Controller with
Video DAC
Supports NTSC and PAL video for-
mats
Fully configurable by user
9-bit Video DAC and 8x Video PLL
High operating frequencies
Up to 36 MHz for SPI
The VLSI Solution VS23S010C-L is an easy-
to-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.
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 General Purpose I/O pins
SPI Single, Dual, or Quad operation and
simultaneous Video Display Controller
8-bit Parallel Interface operation
8-bit Parallel Interface operation and si-
multaneous Video Display Controller
Applications
Microcontroller RAM extension
VoIP and internet data stream buffer
Audio data buffer
Video frame buffer
Over 35 MHz for Video Display Con-
troller
1
15 MHz for 8-bit parallel interface
(TBD) MHz for SRAM writes when
Video Display Controller enabled
Active Low-power
Read current 200 µA at 1 MHz (Sin-
gle I/O, SO=0, TA=+85C, VDD=3.3V)
