Product details
Overview
UPD30550AF2-400-NN1-A from NEC Electronics is a 64-/32-bit MIPS64 RISC microprocessor operating at 400 MHz internal clock (133 MHz external bus), featuring on-chip FPU, 64 kB primary cache (32 kB instruction + 32 kB data), 48-entry TLB, and BGA-272 package. It supports selectable 64/32-bit system bus width and VR5000/VR5432 protocol compatibility for high-end embedded computing.
For engineers reviewing the UPD30550AF2-400-NN1-A datasheet, UPD30550AF2-400-NN1-A pinout, UPD30550AF2-400-NN1-A application, or UPD30550AF2-400-NN1-A equivalent, key selection factors include core voltage (1.6–1.7 V), I/O voltage options (2.5 V or 3.3 V), bus mode configuration at reset, and JTAG/N-Trace debug interface support.
Technical Context
The UPD30550AF2-400-NN1-A implements a two-way superscalar super-pipeline architecture compliant with MIPS I–IV instruction sets, including sum-of-products, rotate, and low-power instructions. Its internal 400 MHz clock is derived from SysClock via programmable ×2 to ×5.5 multiplication using DivMode(2:0) pins.
It integrates separate core (VDD) and I/O (VDDIO) power domains, with dedicated quiet PLL supplies (VDDPA1/VSSPA1, VDDPA2/VSSPA2). The system interface supports both normal and out-of-order return modes, configurable via O3Return#, DWBTrans#, DisDValidO#, and BusMode pins - all latched at reset and non-volatile during operation.

Pinout & Package
272-pin plastic BGA (C/D advanced type), 29 mm × 29 mm body size, 1.0 mm ball pitch. Pinout conforms to µPD30550AF2-400-NN1-A bottom-view layout as specified in Document U16678EJ3V0DS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| BusMode | Bus width configuration input | Static input sampled at reset: high = 64-bit, low = 32-bit; determines SysAD[63:32] and SysADC[7:4] usage |
| VDD / VDDIO / VDDPA1 / VDDPA2 | Power supply terminals | Four independent supply domains: core (1.6–1.7 V), I/O (2.5/3.3 V), and dual quiet PLL rails - each requiring local decoupling |
| JTCK / JTMS / JTDI / JTDO / JTRST# | JTAG test interface | IEEE 1149.1-compliant boundary-scan and debug access; JTCK max 33 MHz, asynchronous to SysClock |
| NTrcClk / NTrcData[3:0] / NTrcEnd | Real-time trace interface | Non-intrusive instruction/data trace output synchronized to SysClock; enables cycle-accurate software profiling |
Key Features
| Feature | Design Value |
|---|---|
| 64-/32-bit configurable bus | Enables backward compatibility with VR5000-series designs while supporting higher bandwidth in new 64-bit systems |
| On-chip FPU and MACU | Hardware-accelerated floating-point and multiply-accumulate operations eliminate need for external coprocessors in signal processing |
| Two-way superscalar pipeline | Simultaneous issue of up to two instructions per cycle improves IPC over scalar predecessors without increasing clock frequency |
| Out-of-order return mode | Allows external memory controller to reorder responses, reducing average memory latency in burst-intensive workloads |
| Hardware debug (N-Wire) | Integrated JTAG + N-Trace provides non-intrusive real-time visibility into execution flow, critical for deterministic embedded debugging |
| Programmable clock multiplier | DivMode(2:0) selects ×2 to ×5.5 internal/external clock ratio, enabling flexible clock tree design across multiple board variants |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RISC microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UPD30550AF2-300-NN1-A | 300 MHz core clock, 1.5 V ±5% core supply, 603 MIPS performance | Lower thermal envelope and power consumption; suitable for cost-sensitive or thermally constrained designs | Select when system workload does not require 400 MHz throughput and board-level cooling is limited |
| UPD30550AGD-350-WML-A | QFP-208 package, 350 MHz core, fixed 32-bit bus, no BusMode or O3Return# support | Limited to 32-bit legacy interfaces; lacks out-of-order return and bus-width flexibility of BGA variant | Choose only if PCB layout constraints prohibit BGA or existing QFP socket infrastructure must be reused |
Compared with UPD30550AF2-400-NN1-A, the 300 MHz variant trades peak performance for lower power and voltage margin, while the QFP-350 part sacrifices configurability and debug capability for package compatibility - neither offers pin-to-pin or functional equivalence.

FAQ
What is the maximum operating frequency of the UPD30550AF2-400-NN1-A?
The UPD30550AF2-400-NN1-A operates at an internal core frequency of 400 MHz, with a maximum external system bus clock of 133 MHz. This is achieved using the on-chip PLL with DivMode(2:0) pins configured for ×3.0 multiplication of a 133 MHz SysClock input. The device is fully characterized and guaranteed at this speed under specified voltage and temperature conditions.
Does the UPD30550AF2-400-NN1-A support both 32-bit and 64-bit system bus modes?
Yes, the UPD30550AF2-400-NN1-A supports both 32-bit and 64-bit system bus widths. The BusMode pin is sampled at reset to select the mode: high enables full 64-bit SysAD(63:0) and SysADC(7:0), while low restricts operation to SysAD(31:0) and SysADC(3:0). This configuration is static and cannot be changed dynamically during operation.
What power supply voltages are required for the UPD30550AF2-400-NN1-A?
The UPD30550AF2-400-NN1-A requires four distinct supply rails: VDD (core) at 1.6–1.7 V, VDDIO (I/O) at either 2.5 V ±5% or 3.3 V ±5%, and two quiet PLL supplies VDDPA1 and VDDPA2 (each 1.6–1.7 V). All supplies must be ramped within 100 ms of each other; violating this sequencing risks functional failure.
Is the UPD30550AF2-400-NN1-A pin-compatible with other VR5500A variants?
Yes, the UPD30550AF2-400-NN1-A shares identical pinout and package (272-pin BGA) with UPD30550AF2-300-NN1-A and all VR5500A family members. Electrical and timing specifications differ by speed grade, but PCB layout, power delivery, and signal routing are fully interchangeable - enabling drop-in replacement for performance scaling or qualification testing.
What debug interfaces does the UPD30550AF2-400-NN1-A provide?
The UPD30550AF2-400-NN1-A provides IEEE 1149.1 JTAG (JTCK/JTMS/JTDI/JTDO/JTRST#) for boundary-scan and core debug, plus an N-Trace interface (NTrcClk/NTrcData[3:0]/NTrcEnd) for real-time instruction and data trace. Both interfaces operate independently of the main CPU clock and support non-intrusive firmware analysis during live operation.
