Detailed Description

4.5Mbit synchronous dual-port SRAM, 256K x 18 organization, 3.3V supply, 133 MHz clock. Industrial temperature grade (-40°C to +85°C), surface-mount 120-pin TQFP/LQFP (14 x 14 mm) package. Parallel interface, volatile memory. RoHS3 compliant. Base product number CY7C0832. Packaged in trays. Ideal for two-processor shared memory with deterministic high-speed access.

Key Features

Synchronous dual-port SRAM with separate Port A and Port B for concurrent access

256K x 18 bit organization (18-bit data bus per port)

133 MHz maximum clock rate for fast transactions

3.3V operation (3.135V to 3.465V supply range)

Parallel interface, LVTTL-compatible I/O

Industrial temperature support (-40°C to +85°C)

Arbitration and semaphore features typical of DP SRAMs (busy flags/lock mechanisms) to prevent bus contention

Byte write support and three-state outputs

Multiple power and ground pins for stable high-speed operation

RoHS3 compliant, lead-free finishes

Key Advantages

True dual-port design enables simultaneous read/write by two masters without external logic

High speed and synchronous operation reduce latency and simplify timing closure

Deterministic access with built-in conflict resolution improves system reliability

Mature ecosystem and long field history increase design confidence

Industrial-grade temp range supports harsh environments

18-bit bus per port fits designs needing parity or wider data paths

Packaging

Type: 120-pin TQFP/LQFP, tray

Body size: 14 x 14 mm nominal

Material: Molded epoxy plastic package with copper leadframe, lead-free plating (RoHS3)

Pin configuration: 120 gull-wing leads around the perimeter; separate address/data/control groups for Port A and Port B; multiple VDD/VSS pins distributed for signal integrity

Mounting: Surface mount

Thermal characteristics: No exposed thermal pad; thermal performance depends on PCB copper and airflow; operates -40°C to +85°C ambient (TA)

Electrical properties: 3.135V to 3.465V supply, LVTTL I/O, 133 MHz clock, parallel synchronous interface, tri-state outputs

Lifecycle

Status: Mature, widely used dual-port SRAM family. Availability and lifecycle can vary by speed grade and package.

Not confirmed near discontinuation at the time of writing, but always check current status.

Equivalent or alternative models (verify pinout, timing, and temp grade before use):

- Same family and density:

- CY7C0832V-133AXC (commercial temp range variant)

- CY7C0832V-100AXI (100 MHz speed grade, industrial temp)

- CY7C0832V-133AXI in different packing options (e.g., tape-and-reel availability; contact us)

- Related vendors (functionally similar dual-port SRAM; not guaranteed pin-compatible):

- Renesas/IDT 70V3579 (256K x 18, 3.3V, synchronous DP SRAM)

- ISSI IS65 series 256K x 18 synchronous dual-port SRAM (model varies by speed and package)
