Infineon Technologies CY7C1462AV33-200AXI

Overview

CY7C1462AV33-200AXI from Cypress Semiconductor is a 3.3V synchronous pipelined SRAM with NoBL™ architecture, configured as 2M × 18 (36 Mbit), supporting 200 MHz bus operations with zero wait states and 3.2 ns maximum access time. It features fully registered inputs/outputs, byte write capability via BWa–BWb, and synchronous self-timed writes for back-to-back Read/Write transitions in high-throughput networking buffers.

For engineers reviewing the CY7C1462AV33-200AXI datasheet, CY7C1462AV33-200AXI pinout, CY7C1462AV33-200AXI application, or CY7C1462AV33-200AXI equivalent, key selection considerations include burst mode support (linear/interleaved), ZZ sleep mode, JTAG boundary scan compliance, and 165-ball FBGA package compatibility with ZBT-style system designs.

Technical Context

The CY7C1462AV33-200AXI implements a No Bus Latency™ architecture enabling true consecutive Read/Write operations without wait states, using on-chip address counters advanced by ADV/LD and qualified by CEN-controlled CLK. All synchronous signals-including address, byte write selects, and control inputs-are latched on the rising edge of CLK.

It supports two burst orders (linear and interleaved) selected by MODE pin state, integrates IEEE 1149.1 JTAG boundary scan with TAP controller and instruction set, and uses synchronous output registers with tristate control masked during write data cycles to prevent bus contention.

FAQ

What is the function of the MODE pin on CY7C1462AV33-200AXI?

The MODE pin selects burst address order: grounded for linear burst (sequential increment), or tied to VDD/floating for interleaved burst (bit-swapped increment). This matches legacy ZBT protocol requirements or modern cache-line alignment needs without external logic.

Does CY7C1462AV33-200AXI support partial writes without read-modify-write cycles?

Yes - BWa and BWb pins enable independent 9-bit segment writes to DQa/DQPa and DQb/DQPb groups. When asserted low with WE active, only the selected byte group is updated, eliminating need for external read-modify-write sequences.

How does the ZZ pin affect power consumption and data retention?

Asserting ZZ low reduces CMOS standby current to ≤120 mA while maintaining full data and register state. Core and I/O supplies remain powered; clock and control logic halt. Data retention is guaranteed over commercial temperature range (0°C to +70°C) with VDD ≥ 2.7 V.

Is CY7C1462AV33-200AXI pin-compatible with ZBT SRAMs?

Yes - it is pin-compatible and functionally equivalent to standard ZBT SRAMs (e.g., IDT ZBT series), sharing identical pinouts, timing protocols, and burst behaviors. This enables drop-in replacement in existing ZBT-based designs without layout or firmware changes.
