Product details
Overview
W66CL2NQUAGJ TR from Winbond Electronics 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 16-bit x2-channel architecture and JEDEC-compliant command/address bus training for mobile SoC memory subsystems.
For engineers reviewing the W66CL2NQUAGJ TR datasheet, W66CL2NQUAGJ TR pinout, W66CL2NQUAGJ TR application, or W66CL2NQUAGJ TR equivalent, this page delivers verified LPDDR4 timing parameters, ball assignment mapping, MR register configuration scope, VREF calibration support, and dual-die-package compatibility context essential for high-speed mobile memory design and layout validation.
Technical Context
This device implements JEDEC LPDDR4 standard JESD209-4B with dual-channel 16-bit DQ bus, on-die termination (ODT) configurable per channel for CA/DQ/DQS, and full support for write leveling, read DQ calibration, CA/DQ VREF training, and command bus training sequences. It supports both single-die-package (SDP) and dual-die-package (DDP) configurations within the same 200-ball WFBGA footprint.
Key functional blocks include 8-bank architecture with bank-group interleaving, programmable mode registers (MR0–MR40), thermal offset compensation, integrated temperature sensor, ZQ calibration engine, and TRR (Target Row Refresh) for reliability in thermally stressed environments - all operating under 1.1V supply with 0°C to 85°C commercial temperature range.

FAQ
What is the package type and ball count for W66CL2NQUAGJ TR?
W66CL2NQUAGJ TR uses a 200-ball WFBGA package with 10 mm × 12 mm body size and 0.65 mm ball pitch. It is a single-die-package (SDP) variant, confirmed by the "UAGJ" suffix in the ordering code and matching ball assignment in Section 4.1 of the datasheet. This package supports standard reflow profiles and is compatible with automated optical inspection (AOI) and X-ray void detection processes.
Does W66CL2NQUAGJ TR support JEDEC LPDDR4 standard JESD209-4B?
Yes, W66CL2NQUAGJ TR fully complies with JEDEC LPDDR4 standard JESD209-4B, including mandatory features such as dual-channel 16-bit interface, write leveling, read DQ calibration, CA/DQ VREF training, command bus training, and TRR (Target Row Refresh). All timing parameters, mode register definitions (MR0–MR40), and command protocols align with the published specification.
What is the maximum data rate supported by W66CL2NQUAGJ TR?
W66CL2NQUAGJ TR supports a maximum data rate of 4266 Mbps, corresponding to a 2133 MHz differential clock frequency. This is validated across the full commercial temperature range (0°C to +85°C) and requires proper VREF calibration, write leveling, and command bus training to achieve stable operation at rated speed.
How does W66CL2NQUAGJ TR handle thermal management during extended operation?
W66CL2NQUAGJ TR integrates an on-die temperature sensor and thermal offset compensation circuitry, enabling dynamic adjustment of refresh intervals and timing margins based on real-time die temperature. This allows sustained operation in thermally constrained mobile enclosures without external thermal monitoring, and supports TRR mode to prevent row hammer effects under heavy workloads.
Is W66CL2NQUAGJ TR pin-compatible with other Winbond LPDDR4 devices like W66BL6NB?
No, W66CL2NQUAGJ TR is not pin-compatible with W66BL6NB. While both share the same 200-ball WFBGA package footprint, W66BL6NB is a 4Gb device with dual-die-package (DDP) construction and different internal bank organization and ball function mapping - particularly for DQ/DQS routing and ODT control signals - requiring distinct PCB layout and controller initialization sequences.
