Product details
Overview
CY7C1011CV33-10BAJXE from Infineon Technologies (formerly Cypress) is an automotive-grade 2-Mbit (128 K × 16) CMOS static RAM with 10 ns access time, 3.3 V ±10% supply, and –40 °C to +125 °C operation. It supports independent byte write via BLE/BHE, automatic CE-controlled power-down, and low active power (468 mW max), deployed in engine control units and ADAS domain controllers.
For engineers reviewing the CY7C1011CV33-10BAJXE datasheet, CY7C1011CV33-10BAJXE pinout, CY7C1011CV33-10BAJXE application, or CY7C1011CV33-10BAJXE equivalent, key selection criteria include tAA = 10 ns read timing, ISB2 = 15 mA CMOS standby current, dual-byte enable architecture, and Pb-free 48-ball BGA packaging for high-reliability automotive memory subsystems.
Technical Context
This SRAM implements a synchronous, address-decoded 131,072 × 16-bit array with separate I/O0–I/O7 (low byte) and I/O8–I/O15 (high byte) data paths controlled by BLE and BHE. Read/write operations are initiated by CE and OE/WE logic combinations, with output enable and chip enable both supporting high-impedance tri-state control.
It features two distinct power-down modes: ISB1 (TTL-compatible CE threshold) draws 45 mA, while ISB2 (CMOS-compatible CE threshold) reduces current to 15 mA. All timing parameters-including tDOE = 6 ns and tHZOE = 5 ns-are specified over full automotive temperature range with 30 pF load and 3 ns signal transition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2 Mbit (128 K × 16) - supports 16-bit parallel bus interface without external multiplexing |
| Access time (tAA) | 10 ns - enables direct interfacing with 100 MHz microcontrollers in real-time control loops |
| Supply voltage | 3.3 V ±10% - compatible with standard automotive 3.3 V power rails and LDO outputs |
| Operating temperature | –40 °C to +125 °C (Automotive-E grade) - qualified for under-hood ECU deployment |
| Standby current (ISB2) | 15 mA - enables low-power sleep mode in always-on vehicle networks |
| Active power | 468 mW max - limits thermal load in sealed automotive modules with constrained airflow |

| I/O8–I/O15 | High-byte bidirectional data | Driven when BHE = LOW; high-Z when BHE = HIGH or CE = HIGH |
| CE | Chip Enable | Primary device select; initiates automatic power-down when HIGH |
| OE | Output Enable | Controls output buffer enable; does not affect internal memory state |
| WE | Write Enable | Active-LOW write strobe; must be LOW with CE LOW to initiate write cycle |

Key Features
| Feature | Design Value |
|---|---|
| Dual independent byte write | BLE and BHE allow simultaneous or selective 8-bit writes to lower/higher bytes without disturbing other byte |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive SRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS61LV102416AL-10TLI | 10 ns access, 3.3 V, but only commercial temp range (0 °C to +70 °C); no automotive qualification | Not suitable for under-hood use; limited to cabin-only modules | Select only for non-safety, non-thermal-stress applications where AEC-Q100 is not required |
| AS6C1008-10TIN | 10 ns access, 3.3 V, industrial temp (–40 °C to +85 °C); lacks byte-enable pins and automatic power-down | Requires external logic for partial writes; higher standby current (35 mA) | Use where cost is primary constraint and byte masking is unnecessary |
Compared with IS61LV102416AL-10TLI and AS6C1008-10TIN, CY7C1011CV33-10BAJXE uniquely delivers AEC-Q100 Grade 1 qualification, dual-byte write control, and 15 mA ISB2 standby-enabling single-chip memory solutions in thermally demanding automotive domains without design compromises.

FAQ
Is CY7C1011CV33-10BAJXE pin-compatible with CY7C1011DN-10ZSXI?
No. CY7C1011CV33-10BAJXE uses a 48-ball BGA package (0.8 mm pitch), while CY7C1011DN-10ZSXI is a 44-pin TSOP-II package. The ball-to-lead mapping differs significantly, and pin functions such as BLE/BHE placement are not aligned. PCB redesign and layout revision are required for substitution.
What is the maximum clock frequency supported for read/write cycles?
This SRAM has no internal clock; it operates asynchronously. Maximum effective throughput is governed by tRC = 10 ns, enabling up to 100 million read/write cycles per second in burst mode. System-level timing depends on host controller setup/hold margins and board-level signal integrity-not a clock frequency specification.
Does CY7C1011CV33-10BAJXE support JTAG or boundary scan?
No. CY7C1011CV33-10BAJXE is a pure static RAM with no test access port, JTAG controller, or boundary-scan logic. It implements only core memory functions: address decoding, data I/O, and CE/OE/WE control. Debugging relies on external logic analyzers or MCU memory-mapped diagnostics.
Can this part operate at 2.5 V VCC?
No. The device is specified only for 3.3 V ±10% (2.97 V to 3.63 V). Operation below 2.97 V violates the Absolute Maximum Rating for VCC and results in undefined behavior, including data corruption, increased tAA, and failure to enter automatic power-down mode. Data retention is guaranteed only down to 2.0 V-but only after VCC has been within spec during active operation.
