Infineon Technologies CY7C1363C-133AXCT

Overview

CY7C1363C-133AXCT from Infineon Technologies (formerly Cypress) is a 9-Mbit synchronous flow-through SRAM with 512K × 18 organization, designed for high-speed cache and buffer applications in microprocessor systems. It supports 133 MHz bus operation with 6.5 ns clock-to-output delay, operates on 3.3 V core supply (±5%/+10%), and features dual VDDQ options (2.5 V or 3.3 V) for I/O compatibility.

For engineers reviewing the CY7C1363C-133AXCT datasheet, CY7C1363C-133AXCT pinout, CY7C1363C-133AXCT application, or CY7C1363C-133AXCT equivalent, key selection criteria include burst mode flexibility (interleaved/linear), synchronous self-timed write capability, IEEE 1149.1 JTAG support, and TQFP-100 Pb-free packaging with 3-chip-enable configuration.

Technical Context

This SRAM implements a synchronous flow-through architecture with a 2-bit on-chip burst counter that captures the initial address and auto-increments for subsequent burst cycles. All address, data, and control inputs (CE1/CE2/CE3, ADSC/ADSP/ADV, BWx, BWE, GW) are registered on the rising edge of CLK.

Asynchronous signals include OE and ZZ (sleep mode), enabling low-power operation without clock dependency. Burst sequence type-interleaved (MODE = HIGH) or linear (MODE = LOW)-is user-selectable and determines address progression during burst reads/writes initiated by either processor (ADSP) or controller (ADSC) strobes.

FAQ

What is the function of the MODE pin on CY7C1363C-133AXCT?

The MODE pin selects burst address sequencing: a HIGH level configures interleaved addressing (e.g., 0, 4, 2, 6…), matching Intel Pentium protocols, while a LOW level selects linear addressing (0, 1, 2, 3…). This hardware-selectable behavior requires no initialization code and directly affects how ADV-driven burst cycles increment internal addresses.

Does CY7C1363C-133AXCT support both 2.5 V and 3.3 V I/O interfaces simultaneously?

No-it supports either 2.5 V or 3.3 V on VDDQ, selected at power-up and fixed for the duration of operation. The I/O voltage must be externally supplied to the VDDQ pins and matched to the host interface voltage; mixing voltages across DQ pins is not permitted and may damage the device.

How does the ZZ (sleep) mode reduce power consumption?

When ZZ is driven LOW asynchronously, the device enters deep power-down mode, disabling internal clocks, sense amplifiers, and output drivers. Typical standby current drops to less than 60 µA-over 600× lower than active standby-while retaining full data retention and enabling instant wake-up on CE or CLK activity.

Can CY7C1363C-133AXCT be used with a 100 MHz clock in a 133 MHz-rated part?

Yes-the 133 MHz rating guarantees correct operation up to 133 MHz; running at 100 MHz is fully compliant and reduces timing margin pressure. Electrical characteristics including tCO (6.5 ns) and setup/hold times remain valid, and all features-including burst modes, JTAG, and ZZ sleep-operate identically at lower frequencies.
