Product details
Overview
CY7C1059DV33-10ZSXI from Infineon Technologies (formerly Cypress) is a 8-Mbit (1M × 8) high-speed CMOS static RAM with 10 ns access time, 3.3 V supply, and automatic CE-controlled power-down. It features TTL-compatible I/O, tri-state outputs, and supports memory expansion via dedicated CE, OE, and WE control lines. Used in industrial embedded controllers requiring deterministic low-latency data storage.
For engineers reviewing the CY7C1059DV33-10ZSXI datasheet, CY7C1059DV33-10ZSXI pinout, CY7C1059DV33-10ZSXI application, or CY7C1059DV33-10ZSXI equivalent, key selection criteria include tAA ≤ 10 ns, ISB2 ≤ 20 µA (CMOS standby), VCC = 3.3 V ±0.3 V, 44-pin TSOP-II package with center power/ground pinout, and industrial temperature range (–40°C to +85°C).
Technical Context
The device implements a fully asynchronous SRAM architecture with independent address decoding, sense amplifiers, and input/output buffers. All control signals-CE, OE, and WE-are active-low and fully compatible with TTL logic thresholds, enabling direct interfacing with legacy microcontrollers and FPGAs without level shifting.
Power management is handled through dual standby modes: ISB1 (TTL-input mode, ≤40 mA) and ISB2 (CMOS-input mode, ≤20 µA), triggered automatically when CE is deasserted. Data retention operates down to 2.0 V with ICCDR ≤20 mA, supporting brown-out resilience in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tAA | 10 ns maximum - guarantees data valid within 10 ns of stable address, enabling 100 MHz bus operation |
| VCC | 3.3 V ±0.3 V - requires tight regulation; incompatible with 2.5 V or 5 V rails without translation |
| ISB2 | 20 µA maximum - ultra-low standby current enables long-term retention in power-constrained systems |
| Operating Temp | –40°C to +85°C - qualified for industrial environments without derating |
| Package | 44-pin TSOP-II (ZS suffix) - surface-mount, center VCC/VSS pinout reduces noise coupling |
| Memory Organization | 1M × 8 bits - single-byte-wide interface simplifies byte-aligned addressing in 8-bit microcontrollers |
| VDR | 2.0 V minimum - supports data retention during partial power loss or controlled shutdown sequences |
Pinout & Package
44-pin TSOP-II (Thin Small Outline Package, Type II) with center power/ground pinout: VCC and VSS pins are located centrally (pins 16/17 and 31/32), minimizing simultaneous switching noise and improving signal integrity on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address inputs | 20-bit address bus supporting full 1M-word decoding; no internal multiplexing |
| I/O0–I/O7 | Bidirectional data bus | Tri-state capable; high-impedance when CE HIGH, OE HIGH, or WE LOW |
| CE | Chip Enable (active LOW) | Primary device select; triggers automatic power-down when HIGH |
| OE | Output Enable (active LOW) | Controls output buffer enable; does not affect power state |
| WE | Write Enable (active LOW) | Initiates write cycle; must be LOW with CE LOW; OE may be HIGH or LOW |
| VCC / VSS | Supply / Ground | Pins 16, 17 (VCC), 31, 32 (VSS) - center location reduces IR drop and EMI |
Key Features
| Feature | Design Value |
|---|---|
| 10 ns access time | Enables direct attachment to 100 MHz synchronous buses without wait states |
| 20 µA CMOS standby current | Reduces system-level quiescent power by >95% vs. standard TTL-compatible SRAMs |
| 2.0 V data retention | Permits graceful shutdown and battery-backed operation without external backup circuitry |
| TTL-compatible I/O | Eliminates need for level shifters when interfacing with legacy 5 V microcontrollers or CPLDs |
| Center VCC/VSS TSOP-II | Improves power delivery stability and reduces ground bounce in high-speed parallel interfaces |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed parallel SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C8008-10ZIN | 10 ns tAA, but 5 V tolerant I/O; ISB2 = 50 µA; no 2.0 V data retention | Requires level translation for 3.3 V systems; unsuitable for brown-out retention | Select only if interfacing with mixed-voltage 5 V/3.3 V buses and retention not required |
| IS61LV10248-10TLI | 10 ns tAA, 3.3 V only, ISB2 = 15 µA, but uses 48-pin SOJ package (not TSOP-II) | Larger footprint; incompatible pinout prevents drop-in replacement | Choose when lower standby current is critical and board layout allows SOJ rework |
Compared with AS6C8008-10ZIN and IS61LV10248-10TLI, CY7C1059DV33-10ZSXI uniquely combines 2.0 V data retention, center-pin TSOP-II layout, and industrial-grade 3.3 V operation-making it optimal for space-constrained, power-aware embedded systems where deterministic timing and brown-out resilience are mandatory.

FAQ
Is CY7C1059DV33-10ZSXI pin-compatible with earlier CY7C1059DV33 variants?
Yes - all CY7C1059DV33 variants (including -10ZSXI, -12ZSXI, and legacy -10ZS) share identical 44-pin TSOP-II pinout, address/data/control signal mapping, and electrical interface. The "X" suffix denotes lead-free packaging; "I" indicates industrial temperature grade. No PCB redesign is needed for migration.
Does this SRAM require an external clock or refresh circuitry?
No - the CY7C1059DV33-10ZSXI is a true static RAM with no refresh requirement. It operates asynchronously using only CE, OE, and WE control signals. Clock-free operation eliminates jitter sensitivity and simplifies timing closure in FPGA- or MCU-based systems.
Can I use CE HIGH to enter data retention mode while maintaining VCC at 3.3 V?
Yes - asserting CE HIGH places the device in automatic power-down mode (ISB2 ≤20 µA) while retaining full data integrity at VCC = 3.3 V. Data retention voltage (2.0 V) applies only during brown-out conditions; normal operation at 3.3 V with CE HIGH is fully supported and specified.
What is the maximum sustained operating frequency for burst reads?
The device supports continuous read cycles at up to 100 MHz, limited by tRC = 10 ns. For back-to-back reads with OE-controlled timing (Read Cycle No. 2), tDOE = 5 ns and tHZOE = 6 ns allow overlapping accesses without bus contention, provided address setup/hold times are met per AC specifications.
