100-LQFP footprint and board integration
The CY7C1460KV25-167AXC is a 36Mbit synchronous SRAM in a 100-LQFP package (14x20 mm body, 0.5 mm pitch). Surface-mount assembly requires a standard reflow profile for the TQFP footprint; the exposed pad is not present, so thermal dissipation relies on the leadframe and board copper. The 100-TQFP (14x20) supplier package matches the JEDEC MS-026 standard, and the parallel memory interface routes to a 36-bit data bus plus address and control lines — a 4-layer board is typical for signal integrity at 167 MHz.
167 MHz clock and 3.4 ns access — timing budget
The 167 MHz clock frequency gives a 6 ns cycle time. The 3.4 ns access time (from address to data valid) leaves roughly 2.6 ns of the cycle for setup and hold at the controller — this is the timing margin the PCB trace length and load capacitance eat into. The NoBL™ (No Bus Latency) architecture eliminates dead cycles between reads and writes, so back-to-back transactions at full clock rate are possible without wait states. For a 36-bit wide data path, that translates to 752 MB/s peak bandwidth (167 MHz × 36 bits ÷ 8).
Supply voltage and temperature grade
Operates from a 2.375 V to 2.625 V core supply — a 2.5 V rail with ±5 % tolerance keeps it in spec. The commercial temperature range (0°C to 70°C) suits indoor networking, telecom, and industrial control equipment; not rated for extended industrial or automotive environments. The memory is volatile (SRAM), so data is lost on power-down; a battery-backup or non-volatile alternative is needed if retention is required.
