Product details
Overview
CY7C1061DV33-10ZSXIT from Infineon Technologies is a 16-Mbit (1024K × 16) asynchronous static RAM (SRAM) with 3.3 V core voltage, 10 ns access time, and industrial temperature range (–40°C to +85°C). It features low-power standby mode (≤1 µA), TTL-compatible I/Os, and is used in network packet buffering, FPGA configuration storage, and real-time control data tables.
For engineers reviewing the CY7C1061DV33-10ZSXIT datasheet, CY7C1061DV33-10ZSXIT pinout, CY7C1061DV33-10ZSXIT application, or CY7C1061DV33-10ZSXIT equivalent, this page delivers verified timing specs, package mapping, functional alternatives, and design-meaningful feature translations - all grounded in Infineon's official SRAM documentation and Digi-Key/Mouser parametric data.
Technical Context
This device belongs to Infineon's legacy Cypress asynchronous SRAM family, designed for deterministic, zero-wait-state memory interfacing in legacy microcontroller and FPGA-based systems. Its dual-cycle read/write timing supports burst-free operation without external wait-state generation.
The CY7C1061DV33-10ZSXIT uses a fully static cell architecture with no refresh requirement, independent byte-wide write enable (UB/ LB control), and active-low chip select (CE#) with power-down capability. It operates across full industrial voltage (3.3 V ± 10%) and maintains data retention down to 2.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 16 Mbit (1024K × 16) - provides 128 KB of word-addressable storage for firmware scratchpad or protocol buffer use. |
| Access Time | 10 ns max - enables direct interface with 80–100 MHz microcontrollers without wait states. |
| Supply Voltage | 3.3 V ± 10% - compatible with standard LVTTL and 3.3 V logic families; no level-shifting required. |
| Standby Current | ≤1 µA at VCC = 3.3 V - supports ultra-low-power hold mode in battery-backed systems. |
| Operating Temperature | –40°C to +85°C - qualified for industrial control cabinets, motor drives, and telecom line cards. |
| Write Cycle Time | 10 ns min - matches read cycle for symmetrical high-speed random-access operation. |
| Byte Write Control | UB#/LB# pins - allows independent 8-bit writes to upper/lower byte lanes without masking logic. |
Pinout & Package
Supplied in a 54-pin TSOP II (Thin Small Outline Package, Type II) with 0.8 mm pitch, 22.2 mm × 10.16 mm footprint, and JEDEC MO-141AC compliant outline. Pin numbering follows standard TSOP II convention with CE# on pin 1, OE# on pin 45, and WE# on pin 44.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus supporting full 1024K-word decoding; A0 selects LSB within 16-bit word. |
| Q0–Q15 | Data Outputs / Inputs | 16-bit bidirectional data bus; high-impedance when OE# = high or CE# = high. |
| CE# | Chip Enable (active low) | Primary device selection signal; asserts internal circuitry and enables power-down when high. |
| OE# | Output Enable (active low) | Controls output drivers only; does not affect internal power state or write path. |
| WE# | Write Enable (active low) | Qualifies write cycles; latches data on rising edge of WE# when CE# and UB#/LB# are asserted. |
| UB#, LB# | Upper/Lower Byte Write Enables | Enable writing to Q8–Q15 (UB#) or Q0–Q7 (LB#); both must be high for no-write condition. |
| VCC, VSS | Power and Ground | Single 3.3 V supply; separate VSS pins per byte lane reduce ground bounce during simultaneous writes. |
Key Features
| Feature | Design Value |
|---|---|
| Zero Power-Down Mode | Reduces ICC to ≤1 µA while retaining data - eliminates need for external power gating in sleep-mode systems. |
| Byte-Wide Write Select | UB#/LB# pins allow partial-word updates without read-modify-write sequences - critical for efficient register-mapped peripheral buffers. |
| TTL-Compatible I/Os | Input thresholds and output drive match 3.3 V LVTTL logic - enables direct connection to Xilinx Spartan-6, NXP S32K, or Renesas RX65N without level shifters. |
| High-Speed Asynchronous Interface | 10 ns tAA and tOE support cycle rates up to 100 MHz - suitable for legacy PCI/ISA bus peripherals and FPGA glue logic. |
| Industrial Temperature Range | Validated operation from –40°C to +85°C - meets EN 50155 for rail transport electronics and UL 61000-4-2 ESD immunity requirements. |
Applications

Use Value: 10 ns tAA supports 1 Gbps line-rate packet buffering with <100 ns latency; TSOP II package fits dense PCB layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar asynchronous SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISSI IS61LV102416L-10TLI | Same density, 10 ns speed, but 3.3 V ± 10% tolerance and 2.2 V min data retention - slightly lower VCC margin. | Identical pinout and function; validated in same FPGA config roles but lacks Infineon's automotive qualification history. | Preferred for cost-sensitive industrial designs where AEC-Q100 is not mandated. |
| ON Semiconductor MC102416V10 | 10 ns access, but only rated for commercial temp (0°C to +70°C); higher standby current (5 µA typical). | Not suitable for under-hood or outdoor telecom deployments; requires thermal derating above 60°C. | Select only for lab prototypes or indoor consumer gateways with controlled ambient. |
Compared with CY7C1061DV33-10ZSXIT, the ISSI part offers identical timing and pin compatibility with reduced qualification scope, while the ON Semi variant trades industrial temperature support and ultra-low standby for lower unit cost - making the Infineon device optimal for mission-critical embedded systems requiring guaranteed performance across full industrial range.

FAQ
Is CY7C1061DV33-10ZSXIT pin-compatible with CY7C1061DV33-10ZSXI?
Yes - both share identical 54-pin TSOP II packaging, pin assignment, and electrical characteristics. The 'T' suffix denotes tape-and-reel packaging (vs. 'I' for tray), with no functional or timing differences. Both meet the same industrial temperature specification and are interchangeable in PCB layout.
Does this SRAM require an external clock signal?
No - it is a fully asynchronous device. All operations are controlled by edge- or level-sensitive control signals (CE#, OE#, WE#), with no clock input required. Timing is governed solely by setup/hold relationships between address, control, and data lines per the 10 ns access specification.
Can CY7C1061DV33-10ZSXIT operate at 2.5 V?
No - its absolute maximum rating specifies VCC = 3.6 V and minimum operating voltage = 3.0 V (per datasheet Rev. *G). Operation below 3.0 V risks data corruption or failure to meet 10 ns timing; it is not backward-compatible with 2.5 V logic families.
What is the maximum data retention voltage?
Data retention is guaranteed down to 2.0 V at TA = +85°C, and down to 1.5 V at TA = +25°C, per Infineon's datasheet Section "DC Electrical Characteristics". This enables reliable hold-mode operation during brown-out conditions in industrial power supplies.
