Infineon Technologies CY7C1010DV33-10ZSXIT

Overview

CY7C1010DV33-10ZSXIT from Cypress Semiconductor is a 2-Mbit (256 K × 8) high-speed CMOS static RAM with 10 ns access time, 3.3 V supply, TTL-compatible I/O, and automatic CE-controlled power-down. It operates across –40 °C to +85 °C and supports memory expansion via active-low CE, OE, and WE controls in industrial embedded systems requiring deterministic timing and low standby current.

For engineers reviewing the CY7C1010DV33-10ZSXIT datasheet, CY7C1010DV33-10ZSXIT pinout, CY7C1010DV33-10ZSXIT application, or CY7C1010DV33-10ZSXIT equivalent, key selection criteria include tAA ≤ 10 ns read timing, ISB2 ≤ 10 mA CMOS standby current, 2.0 V data retention capability, and compatibility with 36-pin SOJ and 44-pin TSOP II board layouts.

Technical Context

The device implements a synchronous, non-volatile-retentive SRAM architecture with full address decoding (A0–A17), eight bidirectional I/O lines (I/O0–I/O7), and three-state output drivers controlled by CE, OE, and WE. All control inputs are TTL-compatible with VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 3.3 V ± 0.3 V.

Power management is handled through dual standby modes: ISB1 ≤ 20 mA under TTL input conditions and ISB2 ≤ 10 mA under CMOS input conditions, triggered automatically when CE is deasserted. Data retention is guaranteed down to 2.0 V with ICCDR ≤ 10 mA, enabling low-power hold states without external refresh.

FAQ

What is the maximum operating frequency supported by CY7C1010DV33-10ZSXIT?

The device does not operate on a clock signal but supports up to 100 MHz effective read/write cycle rates, derived from its 10 ns tRC and tWC specifications. System-level timing must respect AC parameters including tACE, tDOE, and tSCE to ensure reliable data capture without violating setup/hold windows.

Does CY7C1010DV33-10ZSXIT require an external clock or refresh circuitry?

No. As a static RAM, it retains data indefinitely while powered and requires no clock input or periodic refresh cycles. Data persistence during power loss is maintained down to 2.0 V VCC, with no external circuitry needed for retention mode entry or exit.

Can CY7C1010DV33-10ZSXIT be used with 5 V logic interfaces?

No - its inputs are TTL-compatible but rated only for 3.3 V operation (VCC = 3.3 V ± 0.3 V). Applying 5 V signals exceeds the absolute maximum input voltage of VCC + 0.3 V (≤3.6 V), risking permanent damage. Level-shifting is mandatory for 5 V system integration.

What is the significance of the 'ZSXIT' suffix in the part number?

The 'ZSXIT' suffix denotes a Pb-free, RoHS-compliant 44-pin TSOP II package with industrial temperature range (–40 °C to +85 °C), center power/ground pinout, and tape-and-reel packaging for automated assembly. It distinguishes this variant from the 36-pin SOJ version (e.g., ZSIT).
