167 MHz synchronous pipeline with 3.4 ns access
The CY7C1370KV33-167AXI is a 18 Mbit NoBL™ synchronous SRAM organized as 512K x 36 bits, clocked at 167 MHz with a 3.4 ns access time from clock rising edge — the pipelined read operation delivers one data word per cycle once the initial latency is satisfied. It operates from a 3.135 V to 3.6 V supply rail and is rated over the industrial temperature range of -40°C to 85°C, which covers thermally demanding environments like outdoor telecom cabinets or factory-floor controllers without derating.
Package, supply rails, and routing checklist
Housed in a 100-lead LQFP (14x20 mm body, 0.5 mm pitch), the package routes to a 100-TQFP footprint per JEDEC MS-026 — the exposed pad on the backside must be soldered to a ground plane for thermal dissipation, and the 0.5 mm pitch demands a 4-layer PCB for clean fan-out of the address and data buses. The parallel memory interface requires all 36 data lines (DQ[35:0]) and 19 address lines (A[18:0]) to be length-matched within the clock period budget; the 3.135 V to 3.6 V supply rail should be decoupled with at least one 100 nF ceramic per supply pin pair plus a bulk 10 µF tantalum within 25 mm of the device.
Active lifecycle and supply posture
The device is ROHS3 compliant and sourced through authorized and independent distribution; availability and current pricing are confirmed at RFQ against the buyer's target quantity.
