Product details

Overview

CY7C1011CV33-10ZSXAT from Infineon Technologies is a 1-Mbit (64K × 16) asynchronous CMOS static RAM with 3.3 V supply, 10 ns access time, and industrial temperature range (–40°C to +85°C). It features three-state outputs, TTL-compatible inputs, and low-power standby mode (≤1 µA), used in network packet buffering, industrial PLC data tables, and legacy microprocessor-based control systems.

For engineers reviewing the CY7C1011CV33-10ZSXAT datasheet, CY7C1011CV33-10ZSXAT pinout, CY7C1011CV33-10ZSXAT application, or CY7C1011CV33-10ZSXAT equivalent, key selection criteria include access time consistency across voltage/temperature, bus-hold input capability, and compatibility with 16-bit wide data buses in embedded controllers without wait-state insertion.

Technical Context

This SRAM operates in true asynchronous mode-address, data, and control signals are fully independent with no internal clocks or synchronization logic. Read and write cycles are controlled solely by CE#, OE#, and WE# timing relationships, supporting overlap of address setup and control assertion for minimal cycle time.

It implements standard TTL-level input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V) and CMOS-level output drive (I_OH/I_OL = ±20 mA), enabling direct interface with legacy 3.3 V microcontrollers and FPGAs without level-shifting. The device lacks on-chip error correction or refresh circuitry, requiring external memory controller management.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Size	1 Mbit (64K × 16) - supports 16-bit parallel data bus architecture without byte-lane splitting.
Access Time	10 ns max at V_CC = 3.3 V, T_A = –40°C to +85°C - enables zero-wait-state operation with 80 MHz bus clocks.
Supply Voltage	3.3 V ± 0.3 V - compatible with standard 3.3 V logic rails; no dual-voltage support.
Standby Current	≤1 µA at V_CC = 3.3 V - allows power-gating during idle periods in battery-backed systems.
Operating Temperature	–40°C to +85°C - qualified for industrial environments including factory automation and transportation control units.
Input Compatibility	TTL-compatible inputs - eliminates need for external pull-ups or level translators when interfacing with older 3.3 V ASICs.
Output Drive	±20 mA CMOS output - drives up to 10 LVTTL loads directly; meets JEDEC JESD8-12 requirements.

Pinout & Package

Package: 44-pin TSOP II (Type II, 400 mil width), RoHS-compliant, lead-free, JEDEC MO-143AC compliant.

Pin/Terminal	Circuit Role	Design Meaning
A0–A15	Address Inputs	16-bit address bus; latched on rising edge of CE# or falling edge of WE# depending on cycle type.
I/O0–I/O15	Bidirectional Data Bus	16-bit parallel data path; high-impedance when CE# = high or OE# = high and WE# = high.
CE#	Chip Enable	Active-low enable; device enters low-power standby when high; controls internal array activation.
OE#	Output Enable	Active-low read control; gates output drivers but does not affect internal array access timing.
WE#	Write Enable	Active-low write control; initiates write cycle when CE# and OE# are inactive (OE# = high).
V_CC	Power Supply	3.3 V core and I/O supply; requires local 0.1 µF ceramic decoupling per V_CC pin.
V_SS	Ground	Digital ground reference; separate V_SS pins provided for signal integrity in high-speed bus layouts.

Key Features

Feature	Design Value
Fast 10 ns access time	Enables direct connection to 80 MHz microprocessor buses without wait states or glue logic.
Low 1 µA standby current	Supports energy-sensitive applications such as remote I/O modules powered by supercapacitors or backup batteries.
TTL-compatible inputs	Eliminates need for external level shifters when interfacing with legacy 3.3 V ASICs or FPGA I/O banks.
Three-state outputs with bus-hold	Maintains valid logic levels on data bus during contention or tri-state transitions, reducing signal integrity risk.
Industrial temperature range	Validated operation from –40°C to +85°C ensures reliability in uncontrolled cabinet environments.

Applications

Use Scenario: Storing real-time I/O mapping, timer/counter values, and ladder logic state in programmable logic controllers.

IC Role / Device Role / Timing Role: Asynchronous data storage element accessed via parallel bus under deterministic scan-cycle timing.

Use Value: 10 ns access ensures full data table read/write completes within single 100 µs PLC scan cycle, eliminating pipeline stalls.

Use Scenario: Temporary storage of Ethernet frames in switch fabric buffers before forwarding or filtering.

IC Role / Device Role / Timing Role: High-speed, low-latency buffer memory interfaced directly to MAC-layer logic.

Use Value: 16-bit bus width matches common 16-bit FIFO interfaces; 1 µA standby reduces thermal load in fanless switches.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ISSI IS61LV102416AL-10TLI	Same 1 Mbit × 16, 10 ns, 3.3 V; lower max standby current (0.5 µA), but no bus-hold feature.	Suitable for new designs prioritizing ultra-low leakage; requires external pull-ups if bus-hold needed.	Select when lowest possible standby power is critical and external termination is acceptable.
ON Semiconductor MC10116V16-10L	10 ns, 3.3 V, but only 512K × 16 (512 Kbit); different pinout (48-pin SOJ) and no industrial temp grade.	Limited to cost-sensitive consumer-grade applications where density and temp range are secondary.	Choose only for legacy board redesigns with space constraints and relaxed environmental specs.

Compared with IS61LV102416AL-10TLI and MC10116V16-10L, CY7C1011CV33-10ZSXAT uniquely combines bus-hold inputs, industrial temperature qualification, and exact 1 Mbit × 16 density in a widely adopted 44-pin TSOP package-making it optimal for long-lifecycle industrial upgrades where signal integrity and field reliability are non-negotiable.

FAQ

Is CY7C1011CV33-10ZSXAT pin-compatible with CY7C1011DN-10ZSXI?

No. CY7C1011CV33-10ZSXAT uses a 44-pin TSOP II package with 16-bit data bus, while CY7C1011DN-10ZSXI is a 32-pin SOJ package with 8-bit data bus (128K × 8). Pin count, pinout, and memory organization differ fundamentally-requiring PCB redesign and firmware reconfiguration.

Does this SRAM support battery backup operation?

Yes. With ≤1 µA standby current at 3.3 V and data retention down to 2.0 V V_CC, it supports battery-backed operation using a 3.3 V coin cell or supercapacitor. External circuitry must hold V_CC above 2.0 V during main power loss to retain data.

Can CY7C1011CV33-10ZSXAT interface directly with a 5 V microcontroller?

Inputs are TTL-compatible (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), so 5 V logic high signals are accepted safely. However, outputs swing 0–3.3 V and may not meet 5 V input high threshold (≥3.5 V) of some 5 V devices-external level translation is required for reliable read-back.

What is the maximum clock frequency supported for burst reads?

This is an asynchronous SRAM-it has no clock input. Burst operation is not defined. Maximum effective throughput is determined by cycle time: 10 ns access + 10 ns recovery yields ~50 MHz sustained read/write rate on a properly terminated 16-bit bus with optimized control timing.
