Product details

Overview

CY7C1011CV33-12ZSXET from Infineon (formerly Cypress) is a 1-Mbit (64K × 16) asynchronous CMOS static RAM with 3.3 V supply, 12 ns access time, and industrial temperature range (–40°C to +85°C). It features three-state outputs, byte-wide data organization, and low-power standby mode (≤1 µA), used in networking control planes, industrial PLCs, and legacy embedded systems requiring fast, non-refreshed memory.

For engineers reviewing the CY7C1011CV33-12ZSXET datasheet, CY7C1011CV33-12ZSXET pinout, CY7C1011CV33-12ZSXET application, or CY7C1011CV33-12ZSXET equivalent, key selection criteria include access time consistency across voltage/temperature, byte-level write enable control, TTL-compatible inputs, and compatibility with legacy 16-bit bus architectures.

Technical Context

This SRAM operates asynchronously-no clock required-and uses separate OE# (output enable) and WE# (write enable) signals for precise read/write timing control. Its dual CE# (chip enable) inputs support hierarchical memory mapping and power-gating in multi-chip systems.

The device implements full address decoding internally and supports concurrent read/write operations only via external bus arbitration. Data retention is guaranteed down to 2.0 V V_CC, and all inputs meet TTL voltage thresholds with hysteresis on CE# and OE# for noise immunity in noisy industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory size	1 Mbit (64K × 16): supports 16-bit parallel data bus without external multiplexing
Access time	12 ns at V_CC = 3.3 V ±0.3 V, T_A = –40°C to +85°C: ensures deterministic timing in real-time control loops
Supply voltage	3.3 V ±10%: compatible with standard LVTTL and 3.3 V logic families
Standby current	≤1 µA at V_CC = 3.3 V, T_A = +25°C: enables ultra-low-power hold mode during system sleep
Operating temperature	–40°C to +85°C: qualified for industrial-grade deployment without derating
Input voltage threshold	V_IL ≤0.8 V, V_IH ≥2.0 V: TTL-compatible interface eliminates level-shifting in mixed-voltage systems

Pinout & Package

Supplied in a 44-pin TSOP II (Thin Small Outline Package) with 0.8 mm pitch, 12.0 mm × 20.0 mm body, and JEDEC MO-141AC compliant footprint.

Pin/Terminal	Circuit Role	Design Meaning
A0–A15	Address inputs	16-bit address bus supporting full 64K word addressing without external latching
IO0–IO15	Bi-directional data I/O	16-bit parallel data path with internal direction control tied to WE# and OE# states
CE1#, CE2#	Chip enable inputs	Active-low dual CE allows hierarchical memory decoding and selective power-down of memory banks
OE#	Output enable	Controls output buffer tri-state independently of write cycle-enables read-modify-write sequences
WE#	Write enable	Edge-triggered write control; data sampled on WE# falling edge with setup/hold timing referenced to address stability
V_CC, V_SS	Power and ground	Dual V_CC/V_SS pairs reduce simultaneous switching noise and improve signal integrity on high-speed buses

Key Features

Feature	Design Value
Byte-wide organization	Independent upper/lower byte control via UB#/LB# pins enables 8-bit sub-word writes without read-modify-write overhead
Low-power standby	1 µA max ICCSB guarantees minimal leakage during extended idle periods in battery-backed or energy-constrained systems
TTL-compatible inputs	V_IL/V_IH thresholds match legacy 5 V TTL logic, enabling direct interfacing with older microcontrollers and FPGAs
Industrial temperature grade	–40°C to +85°C operation validated per AEC-Q100 stress test conditions for long-term reliability in harsh environments

Applications

Industrial PLC Data Buffer

Legacy Network Switch Control Plane

Use Scenario: Storing real-time I/O status and configuration registers in modular programmable logic controllers with deterministic scan cycles.

IC Role / Device Role / Timing Role: Asynchronous SRAM providing zero-wait-state access for CPU instruction fetch and register shadowing during 10 ms scan intervals.

Use Value: 12 ns access time eliminates pipeline stalls; byte-enable capability reduces bus contention during partial register updates.

Use Scenario: Holding MAC address tables and forwarding rules in Layer 2 Ethernet switches using legacy PowerPC or MIPS-based control processors.

IC Role / Device Role / Timing Role: Non-volatile-cached working memory for packet classification engines requiring consistent latency under burst traffic loads.

Use Value: Dual CE# enables dynamic bank isolation during firmware upgrades; TTL input compatibility avoids level-shifters on aging control buses.

Automotive Body Control Module

Medical Diagnostic Equipment Memory Cache

Use Scenario: Storing sensor calibration data and actuator command history in body domain ECUs where EEPROM endurance is insufficient for frequent logging.

IC Role / Device Role / Timing Role: Fast-access scratchpad memory for diagnostic routines running off internal flash, accessed via 16-bit local bus.

Use Value: Industrial temp rating ensures reliability across under-hood thermal cycling; low standby current extends battery life during vehicle sleep modes.

Use Scenario: Caching waveform buffers and real-time processing parameters in portable ultrasound or ECG units with ARM9-based SoCs.

IC Role / Device Role / Timing Role: Low-latency frame buffer for digital signal preprocessing prior to DMA transfer to main DRAM.

Use Value: 16-bit bus width matches SoC AXI interface width; 3.3 V operation aligns with core logic supply, eliminating auxiliary regulators.

Equivalent & Alternatives

The following parts are listed as comparable options for similar asynchronous SRAM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IS61LV102416-10TLI	10 ns access time, same 64K × 16 organization, 3.3 V supply, but only single CE# and no UB#/LB# pins	Lacks byte-select capability; requires external logic for partial writes; lower power consumption in active mode (12 mA vs 15 mA)	Select when strict 10 ns timing is required and byte-level writes are unnecessary
AS6C1008-12ZIN	12 ns access, 128K × 8 organization, 3.3 V, industrial temp, but requires external address multiplexing for 16-bit interface	Requires wider PCB layout and glue logic to emulate 64K × 16 behavior; higher pin count (48-pin TSOP)	Select only if memory density expansion beyond 1 Mbit is needed and board space permits redesign

Compared with IS61LV102416-10TLI and AS6C1008-12ZIN, CY7C1011CV33-12ZSXET uniquely delivers byte-select functionality and dual CE# in a 44-pin TSOP at 12 ns, making it optimal for space-constrained industrial designs requiring flexible partial-word access without added logic.

FAQ

What is the maximum clock frequency supported by CY7C1011CV33-12ZSXET?

This is an asynchronous SRAM and does not use a clock signal. Timing is controlled entirely by address setup/hold, CE#/OE#/WE# assertion timing, and access time specifications. No clock frequency applies-operation is event-driven based on control signal edges and valid address/data windows.

Does CY7C1011CV33-12ZSXET support battery backup operation?

Yes-it retains data down to V_CC = 2.0 V and draws ≤1 µA in standby, making it suitable for battery-backed applications. However, it lacks built-in battery-switching circuitry; external diode-or or power-path controller is required to manage switchover between main supply and backup battery.

Can CY7C1011CV33-12ZSXET be used with 5 V microcontrollers?

Its inputs are TTL-compatible (V_IH ≥ 2.0 V), so 5 V logic outputs can drive CE#, OE#, WE#, and address lines directly. But V_CC must remain at 3.3 V ±10%; applying 5 V will damage the device. Level-shifting is required only for bidirectional data lines if the microcontroller uses 5 V I/O.

Is there a lead-free and RoHS-compliant version of this part?

Yes-CY7C1011CV33-12ZSXET is manufactured in a lead-free, RoHS-compliant TSOP II package with matte tin finish, per Infineon's standard environmental compliance program. The "Z" in the suffix denotes green (halogen-free) and lead-free packaging.
