Product details
Overview
CY7C1020DV33-10ZSXIT from Cypress Semiconductor is a 512 Kbit (32 K × 16) asynchronous CMOS static RAM with 10 ns access time, 3.3 V supply operation, independent byte-wide write control via BHE/BLE, and automatic CE-controlled power-down. It delivers 60 mA active current and 3 mA CMOS standby current, targeting high-speed buffering in industrial embedded controllers and real-time data acquisition systems.
For engineers reviewing the CY7C1020DV33-10ZSXIT datasheet, CY7C1020DV33-10ZSXIT pinout, CY7C1020DV33-10ZSXIT application, or CY7C1020DV33-10ZSXIT equivalent, key selection criteria include tAA = 10 ns read timing, dual-byte enable architecture, 2.0 V data retention capability, and Pb-free 44-pin TSOP II packaging for space-constrained PCB layouts.
Technical Context
The device implements a fully asynchronous SRAM core with separate upper- and lower-byte write enables (BHE/BLE), enabling partial-word writes without external logic. Its CE-driven automatic power-down reduces ISB2 to 3 mA when deselected, while maintaining full compatibility with CY7C1020CV33 for drop-in upgrades.
All timing parameters-including tACE = 10 ns, tDOE = 5 ns, and tHZOE = 5 ns-are specified under industrial conditions (–40 °C to +85 °C) at VCC = 3.3 V ±0.3 V, with input/output voltage thresholds aligned to TTL/CMOS mixed-signal interfacing (VIH = 2.0 V min, VOH = 2.4 V min).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 512 Kbit (32,768 × 16) - supports 64 KB of word-aligned data storage |
| Access Time (tAA) | 10 ns - enables 100 MHz burst read cycles in synchronous bus interfaces |
| VCC Supply Range | 3.3 V ±0.3 V - compatible with standard 3.3 V logic rails and LDO regulators |
| Active Current (ICC) | 60 mA @ 10 ns - defines peak power draw during continuous read/write operations |
| Standby Current (ISB2) | 3 mA - achieved when CE > VCC – 0.3 V and inputs held at valid CMOS levels |
| Data Retention Voltage | 2.0 V - allows low-power hold mode during system sleep without battery backup |
| Input Capacitance | 8 pF - ensures signal integrity up to 100 MHz with minimal trace loading |

Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS61LV51216AL-10TLI | Same density, speed, and voltage; 44-pin TSOP II but with 5 ns tHZOE (vs. 5 ns) and 4 mA ISB2 (vs. 3 mA) | Marginally higher standby current; identical byte-enable architecture and pinout | Select if sourcing flexibility across multiple qualified suppliers is prioritized over minimal ISB2 reduction |
| ON Semiconductor MC68HC908JK3E | Not an SRAM - 8-bit MCU with 2 KB on-chip RAM; no external bus interface or byte-enable pins | Embedded controller with integrated peripherals, not a memory replacement | Only consider for redesigns where external SRAM can be eliminated via on-die memory expansion |
Compared with IS61LV51216AL-10TLI, CY7C1020DV33-10ZSXIT offers 1 mA lower CMOS standby current and tighter tLZOE (0 ns vs. 1 ns), improving power efficiency in duty-cycled systems; MC68HC908JK3E is functionally incompatible as a microcontroller, not a memory substitute.

FAQ
Is CY7C1020DV33-10ZSXIT pin-compatible with CY7C1020CV33?
Yes, CY7C1020DV33-10ZSXIT is pin-and function-compatible with CY7C1020CV33 per the datasheet Feature section. Both share identical 44-pin TSOP II pinout, address/data/control signal assignments, and truth table behavior-enabling direct replacement without PCB revision.
What is the maximum operating frequency supported by this SRAM?
The device does not operate synchronously, so it has no clock input or maximum frequency rating. Its performance is defined by timing parameters: tRC = 10 ns sets the minimum read/write cycle interval, supporting effective burst rates up to 100 MHz when interfaced with appropriately timed control logic.
Can BHE and BLE be asserted simultaneously for full 16-bit writes?
Yes-asserting both BHE and BLE LOW while CE and WE are LOW enables concurrent writing to I/O0–I/O7 and I/O8–I/O15, performing a full 16-bit write. The truth table explicitly lists "Write-All bits" mode under CE = L, WE = L, BLE = L, BHE = L.
Does this part support hot insertion or live swapping?
No-CY7C1020DV33-10ZSXIT lacks hot-swap protection circuitry. Its absolute maximum ratings specify only –0.5 V to VCC + 0.5 V for DC input voltage, and applying signals before VCC stabilization risks latch-up or damage per the 200 mA latch-up current rating.
