Product details

Overview

CY7C1061DV33-10BVJXIT from Infineon Technologies is a 16-Mbit (1 M × 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 byte-wide write control (UB/LB), three-state outputs, and low-power standby mode (≤25 µA). It serves as fast, non-refreshing data buffer in network packet processors and industrial PLC I/O modules.

For engineers reviewing the CY7C1061DV33-10BVJXIT datasheet, CY7C1061DV33-10BVJXIT pinout, CY7C1061DV33-10BVJXIT application, or CY7C1061DV33-10BVJXIT equivalent, this page delivers verified timing specs, validated pin functions, real-world use cases in deterministic control systems, and cross-reference alternatives with documented write-cycle compatibility and address bus width alignment.

Technical Context

This SRAM operates in true asynchronous mode: address setup/hold times are independent of clock, and read/write cycles are controlled solely by CE#, OE#, and WE# timing. It supports concurrent read/write operations via separate upper/lower byte enables, enabling efficient 16-bit data path utilization without external multiplexing.

The device uses CMOS process technology with TTL-compatible inputs and LVTTL-compatible outputs. Its internal architecture includes fully decoded row/column addressing, on-chip address latching during write, and automatic output disable on CE# or OE# deassertion - eliminating bus contention in shared-memory systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Size	16 Mbit (1,048,576 × 16); supports full 16-bit parallel data interface without glue logic.
Access Time	10 ns max at V_CC = 3.3 V ± 0.3 V; ensures sub-100 MHz bus timing margin for FPGA or microcontroller interfaces.
Supply Voltage	3.3 V ± 0.3 V; compatible with standard 3.3 V logic families and eliminates level-shifting in modern embedded designs.
Standby Current	≤25 µA at T_A = 85°C; enables ultra-low-power retention in battery-backed control applications.
Write Cycle Time	10 ns min; matches read cycle timing for seamless burst-mode data logging without inter-cycle gaps.
Operating Temperature	–40°C to +85°C; qualified for industrial automation and transportation control environments.

Pinout & Package

Package: 54-pin TSOP II (Thin Small Outline Package, Type II), 0.8 mm pitch, body width 10.16 mm - optimized for high-density PCB layouts in space-constrained industrial controllers.

Pin/Terminal	Circuit Role	Design Meaning
A0–A19	Address Inputs	20-bit address bus supporting full 1 M-word decoding; no external address demultiplexing required.
DQ0–DQ15	Data I/O	16-bit bidirectional data bus with internal tristate control; compatible with 16-bit microprocessor data paths.
CE#	Chip Enable	Active-low global enable; must be stable before address setup to avoid spurious access or current spikes.
OE#	Output Enable	Active-low read control; disables outputs when high, preventing bus contention during write or idle states.
WE#	Write Enable	Active-low write strobe; initiates write cycle only when CE# and OE# are inactive (high).
UB#/LB#	Upper/Lower Byte Enable	Independent 8-bit write control; allows partial-word writes without read-modify-write overhead.
V_CC, V_SS	Power/Ground	Dual V_CC (pins 27, 47) and dual V_SS (pins 28, 48) reduce IR drop and improve noise immunity.

Key Features

Feature	Design Value
Fast 10 ns access time	Enables direct interfacing with 66–100 MHz microcontrollers and FPGAs without wait states.
Byte-wide write control (UB#/LB#)	Reduces software overhead in mixed-data-size protocols (e.g., Modbus TCP payload handling).
Low standby current (≤25 µA)	Supports >1-year battery backup in fail-safe I/O modules without compromising data retention.
TTL-compatible inputs / LVTTL outputs	Eliminates level translators when interfacing with Xilinx Spartan-7 or NXP i.MX RT1060 peripherals.
Industrial temperature range	Validated operation across thermal cycling in DIN-rail mounted PLC backplanes and motor drive cabinets.

Applications

Industrial PLC I/O Expansion

Network Packet Buffer

Use Scenario: Real-time digital input/output expansion module in modular PLC chassis requiring deterministic 10 µs response latency.

IC Role / Device Role / Timing Role: Primary data buffer between fieldbus controller and isolated I/O ASIC; holds status snapshots and command queues.

Use Value: 10 ns access time ensures full 16-bit register reads/writes within single CPU bus cycle, eliminating pipeline stalls.

Use Scenario: Temporary storage for Ethernet frame payloads in industrial switch ASICs with limited on-die memory.

IC Role / Device Role / Timing Role: External packet buffer for store-and-forward switching; synchronized with MAC-layer DMA bursts.

Use Value: UB#/LB# enables selective overwrite of frame headers or CRC fields without disturbing payload integrity.

Motor Drive Position Lookup Table

Medical Imaging Data Cache

Use Scenario: High-speed interpolation table storage in servo drive firmware for real-time position correction.

IC Role / Device Role / Timing Role: Read-only lookup table accessed by motion controller's hardware interpolator at 20 kHz update rate.

Use Value: Asynchronous operation avoids clock domain crossing issues; 10 ns latency sustains >50 kSPS interpolation throughput.

Use Scenario: Frame buffering in portable ultrasound beamformer modules where power and latency are tightly constrained.

IC Role / Device Role / Timing Role: Dual-port-like behavior achieved via fast CE#/OE# toggling for simultaneous acquisition and display rendering.

Use Value: ≤25 µA standby current extends battery life in handheld diagnostic devices without sacrificing frame-rate consistency.

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 M × 16 organization, 10 ns access, but uses 54-pin TSOP I (wider body, 12.2 mm); higher standby current (100 µA).	Compatible in footprint-constrained designs only if board layout accommodates wider package; less suitable for battery-critical medical devices.	Select when existing PCB has TSOP I land pattern and lower standby current is not required.
Winbond W9825G6JH-10	Synchronous SDRAM (not asynchronous); requires clock, command decoder, and refresh management; 10 ns latency only under optimal burst conditions.	Not drop-in replaceable; demands significant firmware and controller redesign; unsuitable for deterministic real-time systems.	Avoid unless migrating to full synchronous memory architecture with dedicated memory controller support.

Compared with IS61LV102416AL-10TLI, CY7C1061DV33-10BVJXIT offers 75% lower standby current and TSOP II footprint - critical for thermally dense PLC modules. Against W9825G6JH-10, it delivers guaranteed 10 ns latency without clock tree or refresh overhead, preserving real-time determinism.

FAQ

What is the maximum operating frequency supported by CY7C1061DV33-10BVJXIT?

This is an asynchronous SRAM - it has no clock input and therefore no "operating frequency." Its performance is defined by access time (10 ns max) and cycle time (10 ns min), enabling reliable interface with microcontrollers and FPGAs running bus clocks up to 100 MHz, provided setup/hold timing margins are met per datasheet specifications.

Does CY7C1061DV33-10BVJXIT require refresh circuitry?

No. As a static RAM, it retains data indefinitely as long as power is applied and does not require periodic refresh cycles. This eliminates refresh-related timing uncertainty and simplifies system design for real-time deterministic applications such as motion control and safety I/O.

Can UB# and LB# be asserted simultaneously during a write operation?

Yes - asserting both UB# and LB# low enables full 16-bit write mode. The device treats this as a standard word write; no timing penalty or functional restriction applies. This configuration is used for bulk data transfers where entire words are updated in one cycle.

Is CY7C1061DV33-10BVJXIT RoHS compliant and halogen-free?

Yes. Per Infineon's official product change notice (PCN #190012), CY7C1061DV33-10BVJXIT is RoHS-compliant (2011/65/EU) and halogen-free (IEC 61249-2-21), with lead-free matte tin terminations and compliant packaging materials.
