Product details
Overview
CY7C1361KVE33-133AXM from Infineon Technologies is a 9 Mbit synchronous SRAM organized as 512K × 18 bits, operating at 3.3 V with 133 MHz maximum clock frequency and 7.5 ns access time, used in high-speed networking packet buffering and FPGA co-processor memory interfaces.
For engineers reviewing the CY7C1361KVE33-133AXM datasheet, CY7C1361KVE33-133AXM pinout, CY7C1361KVE33-133AXM application, or CY7C1361KVE33-133AXM equivalent, key selection criteria include parallel x18 bus width, flow-through synchronous timing, JTAG boundary-scan support, and industrial temperature range (–40°C to +85°C) compliance.
Technical Context
This SRAM implements a synchronous pipeline architecture with separate address and data registers, supporting burst mode (linear and interleaved) and byte-write enable for partial-word updates. It uses a dual-cycle read/write protocol with registered control inputs (CE#, WE#, OE#) synchronized to K and K# clocks.
The device integrates on-chip termination resistors for data and address lines, supports JTAG IEEE 1149.1 compliance for boundary-scan testing, and features programmable output drive strength (full/½/¼) and slew rate control to minimize signal integrity issues in dense PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS61WV51218BLL-133TQLI | Same 512K × 18 organization, 3.3 V, 133 MHz, but lacks JTAG and on-chip termination | Requires external termination resistors and external boundary-scan test infrastructure | Select when JTAG testability and layout simplification are non-critical |
| Micron MT48LC512M18A2-3B:G | DDR SDRAM (not SRAM), 512M × 18, 3.3 V, 166 MHz, requires refresh and complex controller logic | Suitable only where higher density justifies added controller overhead and latency variability | Select only if >9 Mbit capacity is mandatory and deterministic latency is secondary |
Compared with IS61WV51218BLL-133TQLI, CY7C1361KVE33-133AXM adds JTAG and on-die termination for reduced BOM count and test coverage; versus MT48LC512M18A2-3B:G, it delivers fixed-latency access essential for real-time control loops without refresh management.

FAQ
Is CY7C1361KVE33-133AXM pin-compatible with earlier CY7C1361KV devices?
Yes - it maintains identical pinout and electrical characteristics with CY7C1361KV-133AXC and CY7C1361KV-133AXI, differing only in enhanced process yield and updated qualification per JEDEC JESD47. No PCB or firmware changes are required for drop-in replacement.
Does this SRAM support asynchronous operation?
No - CY7C1361KVE33-133AXM is strictly synchronous; all address, control, and data transitions are registered to the K/K# clock edges. Asynchronous access is not supported, and no CE#-only or OE#-only modes exist.
What is the purpose of the UB# and LB# pins?
UB# (Upper Byte) and LB# (Lower Byte) enable independent write masking for DQ9–DQ17 (upper byte) and DQ0–DQ8 (lower byte). When asserted, they block writes to their respective 9-bit segments, allowing precise partial-word updates without read-modify-write sequences.
Can this device operate at 2.5 V?
No - CY7C1361KVE33-133AXM is specified only for 3.3 V ±0.3 V operation. Operation outside this range violates absolute maximum ratings and may cause data corruption or permanent damage. It is not backward-compatible with 2.5 V logic families.
