Product details
Overview
CY7C10211BN-10ZXCT from Cypress Semiconductor is a 1-Mbit (64K × 16) high-speed CMOS static RAM with 10 ns access time, 5 V supply, and automatic CE-controlled power-down. It supports independent byte write via BHE/ BLE control lines and operates across commercial temperature range (0°C to +70°C). Used in legacy industrial controllers requiring deterministic low-latency memory access.
For engineers reviewing the CY7C10211BN-10ZXCT datasheet, CY7C10211BN-10ZXCT pinout, CY7C10211BN-10ZXCT application, or CY7C10211BN-10ZXCT equivalent, key selection criteria include tAA ≤ 10 ns, dual-byte enable support, TSOP II package compatibility, and 44-pin SOJ/TSOP footprint interchangeability in board-level redesigns.
Technical Context
This SRAM implements a synchronous, non-volatile-independent read/write architecture with fully decoded 16-bit bidirectional I/O and address-mapped 65,536-word space. Its CE/WE/OE/BHE/ BLE control logic enables selective byte writes and tri-state output management without external bus transceivers.
The device uses CMOS process technology to achieve 825 mW max active power at 10 ns speed, with ISB2 standby current as low as 10 mA (CMOS inputs) or 0.5 mA for L-version variants. Thermal resistance ΘJA is 76.89°C/W in 44-pin TSOP II package, confirming suitability for convection-cooled embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 64K × 16 bits - provides 128 KB of contiguous, random-access storage with no refresh overhead. |
| Access Time (tAA) | 10 ns - guarantees sub-100 MHz bus timing margin for 8051, 68K, or Z80-based legacy controllers. |
| Supply Voltage | 5 V ±10% - compatible with standard TTL/CMOS logic rails; no level-shifting required. |
| Operating Current (ICC) | 150 mA max - defines PCB trace width and decoupling capacitor sizing (≥10 µF bulk + 0.1 µF local). |
| Standby Current (ISB2) | 10 mA max (CMOS inputs) - enables low-power sleep modes in battery-backed systems. |
| Input/Output Capacitance | 8 pF - limits trace length to ≤10 cm on 50 Ω impedance-controlled routing for signal integrity. |
| Temperature Range | 0°C to +70°C - validated for commercial-grade industrial automation panels and test equipment. |
Pinout & Package
Package: 44-pin TSOP Type II (0.400-inch width), RoHS-compliant, lead-free (Pb-free) variant per ordering suffix "X".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Inputs | 16-bit address bus interface; full decoding enables direct CPU address mapping without glue logic. |
| I/O1–I/O8 / I/O9–I/O16 | Bidirectional Data Bus (Lower/Upper Byte) | Independent 8-bit data paths allow byte-selective writes-critical for 8-bit microcontroller coexistence. |
| CE | Chip Enable (active LOW) | Primary chip select; initiates automatic power-down when HIGH, reducing system idle power. |
| WE | Write Enable (active LOW) | Controls write initiation; must be LOW with CE LOW and BHE/ BLE LOW to store data. |
| OE | Output Enable (active LOW) | Enables output drivers during reads; HIGH forces I/O pins into high-impedance state for bus sharing. |
| BHE, BLE | Byte High/Low Enable (active LOW) | Selects upper (I/O9–I/O16) or lower (I/O1–I/O8) byte for write/read-enables mixed-width bus interfacing. |
| VCC (Pins 11, 33) | Power Supply | Dual VCC pins reduce IR drop and improve noise immunity on high-current access cycles. |
| VSS (Pins 12, 34) | Ground | Dual ground pins provide low-inductance return path essential for stable 10 ns timing margins. |
Key Features
| Feature | Design Value |
|---|---|
| Automatic CE Power-Down | Reduces ICC to ≤10 mA when CE is deasserted-eliminates need for external power-gating circuitry. |
| Dual-Byte Write Control | BHE/ BLE pins enable independent 8-bit writes without masking logic-saves FPGA/ASIC gate count. |
| High-Speed 10 ns Access | Meets timing closure for 8051 derivatives running at 12 MHz or Z80 at 4 MHz with wait-state-free operation. |
| TSOP II & SOJ Footprint Compatibility | Same 44-pin layout across packages-allows single PCB design supporting both assembly options. |
| Pb-Free Construction | Complies with RoHS Directive 2011/65/EU-certified for use in EU-market industrial equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AS6C1008-10PCN | 1-Mbit (128K × 8), 10 ns, 3.3 V only, no byte enable pins | Requires external byte multiplexing for 16-bit interfaces; incompatible with 5 V systems | Select only if migrating to 3.3 V architecture and redesigning bus interface logic. |
| IS61LV102416-10TL | 1-Mbit (64K × 16), 10 ns, 3.3 V, LVTTL-compatible, same pinout but different power sequencing | Needs level translation for 5 V CPUs; higher standby current (25 µA vs. 10 mA) | Use for new 3.3 V designs where ultra-low standby current is prioritized over voltage compatibility. |
Compared with AS6C1008-10PCN and IS61LV102416-10TL, CY7C10211BN-10ZXCT uniquely supports 5 V operation, built-in byte write control, and seamless integration into legacy 8051/Z80 systems without voltage translation or bus logic redesign.

FAQ
Is CY7C10211BN-10ZXCT pin-compatible with CY7C1021BN-12ZXC?
Yes-both use identical 44-pin TSOP II footprints and share identical pin assignments per the datasheet. The only functional difference is access time: 10 ns vs. 12 ns. No PCB change is needed for speed-grade substitution within the same temperature grade and package type.
Does CY7C10211BN-10ZXCT require external pull-up resistors on BHE/ BLE pins?
No-BHE and BLE are active-Low CMOS inputs with VIH = 2.2 V minimum and VIL = 0.8 V maximum. They interface directly with standard 5 V TTL/CMOS outputs; pull-ups are unnecessary unless floating states must be avoided during reset.
Can CY7C10211BN-10ZXCT operate reliably at 5.5 V?
No-the absolute maximum VCC rating is 7.0 V, but the specified operating range is 5.0 V ±10%, i.e., 4.5 V to 5.5 V. Operation at 5.5 V is permitted per datasheet, but timing parameters (e.g., tAA = 10 ns) are guaranteed only at VCC = 5.0 V ±5% (4.75–5.25 V).
What is the maximum sustained data throughput achievable with CY7C10211BN-10ZXCT?
At 10 ns access time and continuous read/write cycling, peak throughput is 100 MB/s (16 bits × 100 MHz). Real-world sustained throughput is ~75 MB/s due to address setup/hold and cycle overlap constraints defined in the truth table and switching waveforms.
