Product details
Overview
UPD48576209FF-E33-DW1-A from NEC Electronics (now Renesas) is a 576M-bit synchronous double-data-rate low-latency DRAM with 64M-word × 9-bit organization, 8 banks, HSTL I/O interface, and 300 MHz operation (3.3 ns cycle time). It delivers high-density, low-voltage memory for real-time video buffering in broadcast infrastructure equipment.
For engineers reviewing the UPD48576209FF-E33-DW1-A datasheet, UPD48576209FF-E33-DW1-A pinout, UPD48576209FF-E33-DW1-A application, or UPD48576209FF-E33-DW1-A equivalent, key selection factors include its 144-pin TAPE FBGA package, differential CK/DK clocks, QVLD data-valid signaling, programmable output impedance (25–60 Ω), and non-multiplexed address architecture supporting deterministic timing in latency-critical systems.
Technical Context
This device implements a double-data-rate architecture synchronized to differential input clocks (CK/CK# and DK/DK#), with on-die PLL for clock multiplication and jitter tolerance. It uses SRAM-type command decoding with non-multiplexed addresses (A0–A21), bank addressing (BA0–BA2), and burst-length programming (2/4/8).
It supports auto-refresh at 128K cycles per 32 ms across all banks, operates with three independent supply domains (2.5 V VEXT, 1.8 V VDD, 1.5/1.8 V VDDQ), and integrates JTAG boundary scan (IEEE 1149.1) and ZQ-based output impedance calibration for signal integrity in high-speed parallel bus designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Density & Organization | 576 Mbit total; 64M words × 9 bits × 8 banks - enables compact, wide-data-width memory subsystems without external data widening logic |
| Clock Frequency | 300 MHz (tCK = 3.3 ns) - supports sustained 600 MT/s data transfer rate with deterministic timing margins |
| Interface Standard | HSTL Class I I/O - ensures compatibility with high-speed ASIC/FPGA memory controllers using 1.5 V or 1.8 V VDDQ supplies |
| Supply Voltages | VEXT = 2.5 V ± 0.13 V, VDD = 1.8 V ± 0.1 V, VDDQ = 1.5 V ± 0.1 V - decoupled power domains reduce noise coupling between core logic and I/O drivers |
| Refresh Requirement | Auto-refresh: 128K cycles / 32 ms total - meets JEDEC-compliant refresh scheduling for industrial-temperature operation (0–95°C case) |
| Package | 144-pin TAPE FBGA (18.5 mm × 11 mm) - lead-free, fine-pitch ball grid array optimized for high-density PCB routing and thermal dissipation |
| Data Valid Signaling | QVLD output - provides edge-aligned strobe indicating valid DQ output data, eliminating need for external delay-matching circuits |
Pinout & Package
144-pin TAPE FBGA (18.5 mm × 11 mm), lead-free, top-view ball layout with HSTL-compatible I/O voltage levels and dedicated VSSQ/VDDQ planes for DQ noise isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CK, CK# | Differential system clock inputs | Latch all address/control on rising edge of CK; enable precise timing control and reduced clock skew in high-speed synchronous systems |
| DK, DK# | Differential input data clock | Reference WRITE data and DM on both edges; eliminates setup/hold uncertainty versus single-ended clocking |
| QK0, QK0# | Differential output data clock | Edge-aligned with DQ0–DQ8 outputs; provides receiver-synchronous sampling without phase-locked recovery circuitry |
| QVLD | Data valid indicator | Asserted coincident with valid DQ output; enables immediate data capture without fixed latency assumptions |
| DM | Data mask input | Per-byte masking of WRITE data on both DK edges; supports partial writes without read-modify-write overhead |
| ZQ | Impedance calibration reference | Connects to external resistor to set DQ output impedance (25–60 Ω); matches trace impedance for minimized reflections |
| VREF | HSTL input reference | Nominally VDDQ/2; stabilizes input threshold against supply noise, critical for reliable command/address sampling |
| A0–A21, BA0–BA2 | Non-multiplexed address & bank select | Eliminates address multiplexing overhead; enables full row/column/bank specification every cycle for predictable access latency |
Key Features
| Feature | Design Value |
|---|---|
| SRAM-type interface | Non-multiplexed address bus and explicit command encoding (CS#, WE#, REF#) simplify controller logic and eliminate row/column activation sequencing complexity |
| Programmable burst length | 2/4/8-word bursts configurable via mode register - balances bandwidth efficiency and command overhead for varying data block sizes |
| User-programmable output impedance | 25–60 Ω range calibrated via ZQ pin - dynamically matches PCB trace impedance without requiring external termination resistors |
| Differential input/output clocks | CK/CK#, DK/DK#, QK0/QK0# pairs - reject common-mode noise and enable >300 MHz operation with sub-nanosecond timing margins |
| JTAG boundary scan | IEEE 1149.1 compliant (TMS/TCK/TDI/TDO) - enables in-system testability and interconnect verification without physical probe access |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-latency DRAM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IS42S16400F-6BLI | 16M × 16-bit, 166 MHz, 3.3 V LVTTL interface, no QVLD or ZQ calibration | Lower density, slower speed, TTL-level signaling - suitable only for legacy industrial controllers with limited timing margin | Select only if existing design uses 3.3 V logic and cannot accommodate HSTL voltage levels or differential clocks |
| MT47H64M8CB-3:G | 64M × 8-bit, 333 MHz, SSTL-18 interface, on-die termination, no QVLD | Higher speed but lacks QVLD strobe and ZQ calibration - requires external timing compensation and termination networks | Prefer when DDR2 compatibility and higher bandwidth are prioritized over deterministic latency and simplified layout |
Compared with IS42S16400F-6BLI and MT47H64M8CB-3:G, UPD48576209FF-E33-DW1-A uniquely combines QVLD-synchronized output, ZQ-calibrated impedance, and non-multiplexed addressing to minimize controller logic, reduce PCB layer count, and guarantee worst-case latency in real-time imaging systems.

FAQ
What is the maximum operating case temperature for UPD48576209FF-E33-DW1-A?
The UPD48576209FF-E33-DW1-A is rated for operation at a case temperature (Tc) of 0 to 95°C. This specification is validated under continuous operation with all recommended DC and AC conditions met, including VDD = 1.8 V ± 0.1 V, VDDQ = 1.5 V ± 0.1 V, and proper thermal management per the package's 144-pin TAPE FBGA footprint. The device maintains full functionality and timing compliance across this full industrial temperature range.
Does UPD48576209FF-E33-DW1-A support multiplexed addressing?
Yes, UPD48576209FF-E33-DW1-A supports both non-multiplexed and multiplexed address modes. In non-multiplexed mode (default), A0–A21 and BA0–BA2 are used directly for row/column/bank selection. Multiplexed mode is enabled via Mode Register Set (MRS) command and reduces pin count by sharing address lines with control functions - though it increases latency and is rarely used in latency-critical applications where UPD48576209FF-E33-DW1-A is typically deployed.
What is the purpose of the QVLD signal on UPD48576209FF-E33-DW1-A?
The QVLD (Data Valid) signal on UPD48576209FF-E33-DW1-A is an output that indicates when DQ0–DQ8 data is valid and stable relative to QK0/QK0#. It is edge-aligned with the output data clock and eliminates the need for fixed-latency assumptions or complex deskew circuits in the receiving logic. This feature is essential for achieving deterministic read timing in real-time video and radar processing systems using UPD48576209FF-E33-DW1-A.
Can UPD48576209FF-E33-DW1-A operate with a 1.8 V VDDQ supply?
Yes, UPD48576209FF-E33-DW1-A supports either 1.5 V ± 0.1 V or 1.8 V ± 0.1 V for VDDQ, as specified in the Recommended DC Operating Conditions. When using 1.8 V VDDQ, VDD must also be 1.8 V ± 0.1 V, and VREF must track at 0.5 × VDDQ. This dual-VDDQ capability allows system designers to optimize signal integrity and power consumption based on their PCB stackup and noise environment while maintaining full compatibility with the UPD48576209FF-E33-DW1-A's HSTL I/O interface.
How is output impedance calibrated on UPD48576209FF-E33-DW1-A?
Output impedance on UPD48576209FF-E33-DW1-A is calibrated using the ZQ pin, which connects to an external precision resistor (RQ) tied to VSS. The device measures RQ and sets DQ output driver impedance to 0.2 × RQ, yielding a programmable range of 25–60 Ω. This calibration is initiated via Mode Register Set command and eliminates the need for discrete series termination resistors, simplifying layout and improving signal fidelity on high-speed parallel buses interfaced to UPD48576209FF-E33-DW1-A.
