Infineon Technologies CY7C1460KV33-167BZC

Overview

CY7C1460KV33 from Cypress Semiconductor is a 36-Mbit synchronous pipelined SRAM with NoBL™ architecture and on-chip ECC, configured as 1M × 36 or 2M × 18. It supports zero-wait-state 167 MHz bus operation (t_AC = 3.4 ns), features fully registered I/O, byte-write capability, and 3.3-V core/2.5-V or 3.3-V I/O supply. It is used in high-throughput network packet buffers and telecom line-card data path memory.

For engineers reviewing the CY7C1460KV33 datasheet, CY7C1460KV33 pinout, CY7C1460KV33 application, or CY7C1460KV33 equivalent, key selection criteria include burst order control (MODE pin), ECC-enabled soft error resilience, synchronous self-timed write timing, and TQFP-100 package compatibility with ZBT™-legacy systems.

Technical Context

The device implements a fully synchronous, rising-edge-triggered pipeline with input registers for all address/control signals and output registers for DQ/DQP lines. Its NoBL™ logic enables true back-to-back read/write transitions without bus turnaround latency.

On-chip ECC encodes/decodes 36-bit data + 8-bit parity to detect and correct single-bit errors per access. Burst addressing supports both linear and interleaved orders, selected via the MODE strap pin - fixed at power-up and not runtime reconfigurable.

FAQ

Does CY7C1460KV33 require external termination resistors on DQ or CLK lines?

No. The device integrates programmable output drive strength and on-die termination (ODT) support via internal impedance control circuitry. External termination is optional and only recommended for long trace lengths exceeding 8 inches in high-speed layouts. Reference design guidelines in Application Note AN98522 specify layout rules for 167 MHz signal integrity.

Can the MODE pin be changed dynamically during operation?

No. The MODE pin is sampled only at power-up reset and latched internally. Changing its state after initialization has no effect on burst order. Systems requiring runtime burst order switching must use external logic or select a different SRAM family with dynamic mode control.

What happens to stored data during ZZ sleep mode?

Data retention is guaranteed across the full industrial temperature range (–40°C to +85°C) with VDD ≥ 2.2 V and VDDQ ≥ 1.7 V. Current draw drops to ≤10 µA, and all I/O pins enter high-impedance state. Exit time from ZZ to active mode is 20 ns max, with no clock required during wake-up.

Is JTAG boundary scan supported in all operating modes?

Yes. IEEE 1149.1 boundary scan remains fully functional regardless of CEN state, burst mode, or sleep entry. TAP controller operates independently of memory array activity. Scan chain integrity can be verified even while the SRAM performs normal read/write operations.
