16 Mbit asynchronous SRAM — 1M x 16, 10 ns speed grade
The CY7C10612GN30-10ZSXIT is a 16 Mbit asynchronous SRAM from Infineon Technologies, organized as 1M x 16 bits — the word width matches a 16-bit data bus without byte-lane muxing, so it drops straight into the memory map of a 16-bit or 32-bit microcontroller that needs a fast scratchpad or frame buffer. Access time and write-cycle time are both rated at 10 ns. That 10 ns window sets the bus timing margin: a memory controller with a 50 MHz to 66 MHz read strobe has roughly one clock cycle to sample the data output, so the PCB trace delay and capacitive loading on the data lines must stay tight to avoid setup violations.
Package and board-fit — 54-TSOP II, Tape & Reel
Housed in a 54-TSOP II package (0.400-inch body width, 10.16 mm, per and), the SRAM uses a standard thin small-outline footprint with 0.50 mm pin pitch. The Tape & Reel delivery feeds directly into a pick-and-place machine — no tube-handling step, which keeps the assembly line running at full speed. The 54-pin TSOP II layout routes the full 16-bit data bus and 20-bit address bus out to the board.
