Detailed Description

2 Mbit synchronous SDR SRAM organized as 64K x 32. Parallel interface. 3.3 V operation (3.15–3.6 V). 80 MHz clock. 7 ns access time. Commercial temperature range 0°C to 70°C. 100-pin TQFP/LQFP surface-mount package, 14 x 20 mm body. RoHS non-compliant legacy finish. Base product family CY7C1334.

Key Features

Capacity: 2 Mbit (64K x 32)

Type: Volatile SRAM, synchronous SDR

Interface: Parallel, LVTTL-compatible I/O

Speed: 80 MHz clock, 7 ns access time

Supply: 3.15–3.6 V (nominal 3.3 V)

Package: 100-TQFP (14 x 20 mm), surface mount

Operating temperature: 0°C to 70°C (TA)

Memory family: CY7C1334 series

Key Advantages

Fast, deterministic access for real-time systems

Wide 32-bit data bus simplifies high-throughput designs

Stable 3.3 V operation fits common digital logic levels

Mature, well-documented Cypress SRAM architecture

Synchronous timing improves throughput versus asynchronous SRAM

Packaging

Type: 100-pin TQFP/LQFP, surface-mount

Material: Molded epoxy package with copper lead frame

Finish: Legacy tin/lead plating (RoHS non-compliant)

Size: 14 mm x 20 mm body; typical 0.5 mm lead pitch for 100-TQFP

Pin configuration overview:

- Address lines: approximately 16 (A0–A15) to cover 64K locations

- Data bus: 32 bits (DQ0–DQ31)

- Control and timing: CLK, CE#, OE#, WE#, ADV#, byte write enables (BW0#–BW3#), and other standard synchronous SRAM control pins

Thermal characteristics: Typical TQFP thermal resistance; low power dissipation for CMOS SRAM. Use good PCB copper and airflow for best thermal performance.

Electrical properties:

- I/O standard: LVTTL-compatible

- Supply voltage: 3.15–3.6 V

- Operating frequency: up to 80 MHz

- Access time: 7 ns

- Note: Refer to the datasheet for detailed DC/AC limits, current consumption, and exact pin functions.

Lifecycle

Status: Mature legacy Cypress SRAM. Not marked as RoHS; availability can vary by region and date code. Not confirmed nearing discontinuation from the data provided, but supply may be limited due to age.
