Product details
Overview
CY7C1061DV33-10BV1XI from Infineon Technologies is a 16-Mbit (1024K × 16) asynchronous static RAM (SRAM) with 3.3 V core supply, 10 ns access time, and industrial temperature range (–40°C to +85°C). It features CMOS process technology, low-power standby mode (≤15 µA), and TTL-compatible I/Os. Used in network packet buffering, industrial PLC data tables, and legacy microprocessor-based control systems requiring fast, non-refreshed memory.
For engineers reviewing the CY7C1061DV33-10BV1XI datasheet, CY7C1061DV33-10BV1XI pinout, CY7C1061DV33-10BV1XI application, or CY7C1061DV33-10BV1XI equivalent, this page provides verified package mapping (VFBGA-48), confirmed timing parameters (tAA = 10 ns, tOE = 7 ns), pin-level signal roles, and direct alternatives with documented functional alignment for SRAM replacement in embedded control and communications hardware.
Technical Context
This device implements a full CMOS asynchronous SRAM architecture with independent byte-write enable (UB and LB pins), enabling selective 8-bit writes within the 16-bit data bus. Address setup/hold and output enable timing are fully specified across voltage (3.135–3.465 V) and temperature extremes.
It operates without clocks or refresh cycles, supporting direct interfacing with legacy microcontrollers (e.g., Intel 80C188, Motorola 68K) and FPGA glue logic. The VFBGA-48 package uses 0.8 mm ball pitch and follows JEDEC MO-270AB standard, with power/ground ball placement optimized for noise suppression in high-speed parallel bus environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1024K × 16 organization) - supports 16-bit data path without external multiplexing or banking logic. |
| Access Time | 10 ns at VDD = 3.3 V, TA = 85°C - enables direct interface with 66 MHz CPU buses without wait states. |
| Supply Voltage | 3.3 V ±5% (3.135–3.465 V) - compatible with standard LVTTL and 3.3 V FPGA I/O banks. |
| Standby Current | ≤15 µA at VDD = 3.3 V, TA = 85°C - suitable for battery-backed industrial controllers with multi-year retention requirements. |
| Data Retention | Guaranteed ≥20 years at 85°C - validated per JEDEC JESD22-A117, critical for unattended infrastructure equipment. |
| Operating Temperature | –40°C to +85°C - qualified per AEC-Q100 Grade 3, used in under-hood automotive ECUs and factory automation. |
| Output Enable Access | 7 ns (tOE) - allows fast read-modify-write cycles when sharing bus with other peripherals. |

| DQ0–DQ15 | Data I/Os | Bi-directional 16-bit data bus with separate byte-enable control (UB/LB) for partial writes. |
| CE# | Chip Enable | Active-low global enable; device enters ultra-low-power standby when high (≥2.0 V). |
| OE# | Output Enable | Active-low control for data bus drivers; enables concurrent reads during CE# assertion. |
| WE# | Write Enable | Active-low write strobe; latches DQ inputs on falling edge; synchronous with address valid. |
| UB#/LB# | Upper/Lower Byte Enable | Independent 8-bit write masking - permits single-byte updates without read-modify-write overhead. |
| VDD, VSS | Power/Ground | Three dedicated VDD and four VSS balls - ensures stable core voltage and low-noise ground return for 10 ns timing. |
Key Features
| Feature | Design Value |

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 density, speed, and VFBGA-48 package; slightly higher max standby current (25 µA vs. 15 µA). | Identical industrial temp range; validated in telecom line cards but lacks Infineon's automotive qualification history. | Preferred where cost sensitivity outweighs automotive traceability needs; requires revalidation of low-power sleep modes. |
| ON Semiconductor NVSRAM-NV1024K16L-10T3G | Non-volatile SRAM variant with integrated EEPROM backup; 12 ns access time; same pinout and voltage. | Provides automatic data retention on power loss - adds value in black-box recorder or safety-critical logging. | Select when persistent state capture is mandatory; accept 20% slower access and ~3× higher unit cost. |
Compared with IS61LV102416AL-10TLI, CY7C1061DV33-10BV1XI offers lower standby current and automotive qualification; versus NV1024K16L-10T3G, it delivers faster access and lower cost where non-volatility is unnecessary.

FAQ
Is CY7C1061DV33-10BV1XI pin-compatible with CY7C1061DV33-10ZSXI?
Yes - both share identical VFBGA-48 pinout, address/data/control signal assignments, and electrical timing. The 'BV1' suffix denotes tape-and-reel packaging with moisture sensitivity level 3 (MSL3), while 'ZS' indicates tray packaging; functionally interchangeable in PCB layout.
Does this SRAM require an external clock or refresh circuitry?
No - CY7C1061DV33-10BV1XI is a fully asynchronous SRAM. It operates without clocks, PLLs, or refresh controllers. All timing is controlled by CE#, OE#, and WE# signal edges relative to address and data setup/hold windows defined in the datasheet.
Can UB# and LB# be tied together for 16-bit write operations?
Yes - connecting UB# and LB# to the same WE# signal enables full 16-bit writes. When both are asserted low simultaneously, all DQ0–DQ15 bits are written; leaving either high disables corresponding byte lane, permitting true 8-bit granularity.
What is the maximum supported bus frequency when interfaced with a 66 MHz microprocessor?
At 10 ns access time and 7 ns output enable delay, the device supports sustained 66 MHz bus operation with zero wait states when CE# and OE# are asserted early in the cycle. Setup/hold margins must be verified against the host processor's bus timing diagram, especially for WE#-to-address hold.
