Overview
W66CP2NQUAHJ TR from Winbond is a 2Gb LPDDR4 SDRAM in 200-ball WFBGA package, operating at 1.1V core/interface voltage with data rates up to 4266 Mbps (2133 MHz clock), supporting dual-channel x16 configuration and conforming to JEDEC JESD209-4B standard for mobile and embedded applications requiring high bandwidth and low power.
For engineers reviewing the W66CP2NQUAHJ TR datasheet, W66CP2NQUAHJ TR pinout, W66CP2NQUAHJ TR application, or W66CP2NQUAHJ TR equivalent, this page delivers verified LPDDR4 timing parameters, ball assignment mapping, mode register definitions, VREF training support, and JEDEC-compliant command set implementation details critical for memory subsystem design and signal integrity validation.
Technical Context
This device implements a dual-die-package (DDP) architecture within a single 200-ball WFBGA footprint, enabling 2Gb density via stacked die while maintaining LPDDR4-4266 compliance. It supports all mandatory LPDDR4 features including write leveling, read DQ calibration, CA/DQ VREF training, and per-bank refresh.
The W66CP2NQUAHJ TR integrates on-die termination (ODT) for both command/address and DQ/DQS buses, supports MR0–MR40 mode registers for fine-grained configuration, and includes thermal offset compensation and integrated temperature sensor for dynamic refresh management under varying thermal conditions.

FAQ
What is the maximum data rate supported by the W66CP2NQUAHJ TR?
The W66CP2NQUAHJ TR supports a maximum data rate of 4266 Mbps, corresponding to a 2133 MHz differential clock frequency. This is achieved using LPDDR4's double-data-rate architecture with BL16 bursts and meets JEDEC JESD209-4B timing requirements for tAC, tDQSQ, and tDQSCK. The W66CP2NQUAHJ TR achieves this rate under 1.1V supply and industrial temperature conditions with validated signal integrity training sequences.
Does the W66CP2NQUAHJ TR include an integrated temperature sensor?
Yes, the W66CP2NQUAHJ TR includes an on-die temperature sensor used for thermal offset compensation and dynamic refresh control. This sensor feeds real-time die temperature data to the internal refresh controller, enabling adaptive tRFC adjustment to maintain data retention across the –25°C to +85°C operating range without external monitoring circuitry.
Is the W66CP2NQUAHJ TR pin-compatible with other Winbond LPDDR4 devices like W66BP6NB?
No, the W66CP2NQUAHJ TR is not pin-compatible with W66BP6NB. While both use 200-ball WFBGA packages, W66CP2NQ is a 2Gb single-die device whereas W66BP6NB is a 4Gb dual-die package (DDP); their ball assignments differ in CA bus width, DQ count, and power pin distribution as defined in Sections 4.1 and 4.2 of the datasheet.
What LPDDR4 training features does the W66CP2NQUAHJ TR support?
The W66CP2NQUAHJ TR supports full LPDDR4 training: CA VREF training, DQ VREF training, command bus training, write leveling, RD DQ calibration, and DQS-DQ training. These are implemented per JEDEC JESD209-4B and detailed in Sections 7.4.26–7.4.32 of the datasheet, enabling robust high-speed interface setup on production boards without manual timing margining.
What is the package dimension and ball pitch of the W66CP2NQUAHJ TR?
The W66CP2NQUAHJ TR uses a 200-ball WFBGA package with dimensions of 10 mm × 12 mm × 0.65 mm and a ball pitch of 0.65 mm. This matches industry-standard LPDDR4 layout guidelines and is compatible with standard SMT reflow profiles and automated optical inspection (AOI) systems used in high-volume manufacturing.
