Product Summary
The IDT7203L15JI is a dual-port memory buffer with internal pointers that load and empty data on a firstin/first-out basis. The IDT7203L15JI uses Full and Empty flags to prevent data overflow and underflow and expansion logic to allow for unlimited expansion capability in both word size and depth. Data is toggled in and out of the device through the use of the Write (W) and Read (R) pins. The IDT7203L15JI 9-bit width provides a bit for a control or parity at the user’s option. It also features a Retransmit (RT) capability that allows the read pointer to be reset to its initial position when RT is pulsed LOW. A Half-Full Flag is available in the single device and width expansion modes.
