Infineon Technologies CY7C4142KV13-106FCXC

Overview

CY7C4142KV13-106FCXC from Cypress Semiconductor is a 144-Mbit QDR™-IV XP SRAM with 4M × 36 organization, 1066 MHz maximum operating frequency, 8-cycle read latency, and dual independent DDR data ports (A/B) supporting concurrent read/write transactions. It operates at VDD = 1.3 V ± 40 mV and VDDQ = 1.2 V ± 50 mV, and is deployed in high-bandwidth packet buffering for network line cards.

For engineers reviewing the CY7C4142KV13-106FCXC datasheet, CY7C4142KV13-106FCXC pinout, CY7C4142KV13-106FCXC application, or CY7C4142KV13-106FCXC equivalent, key selection criteria include random transaction rate (2132 MT/s), on-die termination programmability, per-bit deskew training, address parity protection, and JTAG 1149.1 compliance for production testability.

Technical Context

This QDR-IV XP SRAM uses an eight-bank architecture enabling one access per bank per clock cycle, with addresses for port A latched on CK rising edge and port B on CK falling edge. Dual DDR data ports (DQA/DQB) operate with separate differential input clocks (DKA/DKB) and output clocks (QKA/QKB), all synchronized to a single SDR control interface.

It integrates on-chip ECC correcting single-bit errors (SER < 0.01 FITs/Mb), bus inversion (programmable per address/data), and ZQ-based output impedance calibration. Address parity (AP) and error flag (PE#) provide real-time integrity monitoring, while LDA#/LDB# and RWA#/RWB# enable synchronous command gating per port.

FAQ

What is the minimum supported VDDQ voltage tolerance for reliable operation?

The device requires VDDQ = 1.2 V ± 50 mV when operating in HSTL/SSTL mode, as specified in JESD8-16A. Operation outside this range risks setup/hold violations on DQ inputs and may cause data corruption during high-speed bursts. The ±50 mV window is validated across temperature (-40°C to +95°C) and process corners.

How does the address parity error flag (PE#) behave after detection?

PE# asserts low immediately upon detecting an address parity mismatch and remains latched low until explicitly cleared by writing to the Configuration Register's PARITY_CLEAR bit. It does not auto-clear on subsequent valid accesses, ensuring persistent error indication for system-level fault logging and recovery sequencing.

Can the ZQ calibration pin be left unconnected during normal operation?

No. ZQ must be connected to a precision 240 Ω ± 1% resistor to ground for output driver impedance calibration. Leaving it floating disables ODT tuning, causing output swing and timing margin degradation - especially critical for 1066 MHz operation where signal integrity margins are tight.

Is bus inversion enabled by default on power-up?

Bus inversion is disabled by default for both address and data buses after power-on reset. It must be explicitly enabled via the Configuration Register's AINV_EN and DINVA/DINVB bits. Default disable ensures predictable startup behavior and avoids unintended polarity reversal during initialization sequences.
