25L1635DM2I

GENERAL DESCRIPTION

The MX25L1635D are 16,777,216 bit serial Flash memory, which is configured as 2,097,152 x 8 internally. When it is in two or four I/O read mode, the structure becomes 8,388,608 bits x 2 or 4,194,304 bits x 4. The MX25L1635D feature a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). Serial access to the device is enabled by CS# input.
When it is in two I/O read mode, the SI pin and SO pin become SIO0 pin and SIO1 pin for address/dummy bits input and data output. When it is in four I/O read mode, the SI pin, SO pin, WP# pin and NC pin become SIO0 pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output.

PERFORMANCE

• High Performance
- Fast read
- 1 I/O: 104MHz & 86MHz with 8 dummy cycles
- 4 I/O: 75MHz with 6 dummy cycles
- 2 I/O: 75MHz with 4 dummy cycles
