Cypress Semiconductor Corp CY7C1069AV33-10BAC

Overview

CY7C1069AV33-10BAC from Cypress Semiconductor is a 2,097,152 × 8-bit (2 M × 8) asynchronous CMOS static RAM with 10 ns access time, 3.3 V ±0.3 V operation, automatic CE-based power-down, and TTL-compatible I/O. It supports high-speed data buffering in embedded controllers and network packet memory where deterministic low-latency read/write cycles are required.

For engineers reviewing the CY7C1069AV33-10BAC datasheet, CY7C1069AV33-10BAC pinout, CY7C1069AV33-10BAC application, or CY7C1069AV33-10BAC equivalent, key selection criteria include tAA = 10 ns timing, dual chip enable (CE1/CE2) logic for hierarchical memory mapping, 2.0 V data retention voltage, FBGA-60 package thermal and density advantages, and ISB2 standby current of 50 µA at CMOS input conditions.

Technical Context

The CY7C1069AV33-10BAC implements a fully asynchronous SRAM architecture with independent address decoding, sense amplifier array, and bidirectional I/O drivers. Its dual CE architecture (CE1 active-low, CE2 active-high) enables selective bank enabling in multi-chip memory systems without external gating logic.

Power management is handled via automatic transition to low-power mode when CE1 is HIGH or CE2 is LOW, reducing ICC to 50 µA (ISB2) under CMOS input conditions. Data retention remains valid down to 2.0 V VCC, supporting graceful power-fail holdover in industrial control modules.

Key Specifications

Pinout & Package

The CY7C1069AV33-10BAC is housed in a 60-ball fine-pitch ball grid array (FBGA) package measuring 8 mm × 20 mm × 1.2 mm (package code 51-85162), with center power/ground distribution and DNU (do-not-use) balls requiring floating or VSS tie-down per datasheet guidance.

FAQ

What is the maximum operating temperature range for CY7C1069AV33-10BAC?

The CY7C1069AV33-10BAC is rated for industrial operation from –40°C to +85°C ambient temperature. This rating is confirmed in the "Operating Range" table on page 4 of the official datasheet (Document #: 38-05255 Rev. *F), and applies to both DC and AC specifications including tAA = 10 ns and ISB2 = 50 µA.

Does CY7C1069AV33-10BAC require an external clock signal?

No. The CY7C1069AV33-10BAC is an asynchronous static RAM and operates without any clock input. All timing is controlled by edge-triggered control signals (CE1, CE2, WE, OE) and address setup/hold windows defined in the AC switching characteristics table (page 4).

Can CY7C1069AV33-10BAC be used with 2.5 V I/O interfaces?

No. The device requires VCC = 3.3 V ± 0.3 V and specifies VIH = 2.0 V minimum and VIL = 0.8 V maximum. Driving inputs below 2.0 V may cause unreliable logic recognition; interfacing with 2.5 V systems requires level translation per the Absolute Maximum Ratings section.

How many address lines does CY7C1069AV33-10BAC have?

The CY7C1069AV33-10BAC has 21 address inputs (A0 through A20), as confirmed by its 2,097,152-word (2²¹) organization. This is explicitly stated in the Functional Description section (page 1) and verified in the TSOP II and FBGA pin configurations (pages 2–3).
