8 and 32 KB SRAMs
4 March 2009, DSP, Micros & Memory
Microchip has announced a family of 8 and 32 KB standalone serial SRAM devices designed to increase a system’s available RAM by adding small, inexpensive external devices. The 23A640, 23K640 (23 x 640), 23A256 and 23K256 (23 x 256) devices feature an SPI interface to increase design flexibility. These devices provide a simple, inexpensive way for designers to add more RAM to their application while keeping the same MCU or, as they require fewer MCU I/O resources, even using a smaller MCU. The serial RAM devices require just four I/O pins as opposed to 16 or 24 pins for a parallel RAM. Additionally, they feature a bus speed of 20 MHz for fast access, and low operating and standby currents to help extend battery life. The 23A640 and 23A256 have an operating voltage range of 1,7–1,95 V, while the 23K640 and 23K256 have an operating voltage range of 2,7–3,6 V. |
