Renesas UPD30200GD-80-LBB-A

Overview

UPD30200GD-80-LBB-A from NEC Electronics is a 64-bit RISC microprocessor based on the MIPS architecture, operating at 80 MHz with 16 KB instruction cache and 8 KB data cache. It features a 32-bit multiplexed address/data bus, 5-stage pipeline execution, and supports integer and floating-point operations with SPECint92 of 48 and SPECfp92 of 36. It is used in embedded controllers for page printers and amusement game machines.

For engineers reviewing the UPD30200GD-80-LBB-A datasheet, UPD30200GD-80-LBB-A pinout, UPD30200GD-80-LBB-A application, or UPD30200GD-80-LBB-A equivalent, this page provides verified technical context, package mapping, real-world timing behavior, cache configuration details, and validated alternative options for legacy system maintenance and replacement design.

Technical Context

The UPD30200GD-80-LBB-A implements the VR4305 variant of the VR Series, using a 5-stage integer pipeline with integrated TLB and dual-cache hierarchy. Its internal PLL generates PClock (100 MHz) and TClock (40 MHz) from a 40 MHz MasterClock under DivMode=10 (1:2:1 ratio), enabling synchronized system interface operation.

It employs a 32-bit multiplexed SysAD bus and 5-bit SysCmd bus for command/data ID signaling, with dedicated JTAG pins (JTCK/JTDI/JTDO/JTMS) supporting boundary-scan testing. The processor uses ColdReset for full initialization and Reset for exception-only reset without register clearing.

The UPD30200GD-80-LBB-A belongs to NEC's VR Series microprocessor line, designed specifically for cost-sensitive, high-reliability embedded applications where MIPS compatibility, integrated cache, and low-power 32-bit system bus integration were critical.

FAQ

What is the correct supply voltage range for UPD30200GD-80-LBB-A?

The UPD30200GD-80-LBB-A requires a nominal 3.3 V supply with tolerance of ±0.3 V (3.0 V to 3.6 V). This specification is explicitly defined in the DC Characteristics table for µPD30200-80 variants and governs I/O voltage levels, power sequencing, and thermal dissipation calculations. Operation outside this range risks functional failure or accelerated wear.

Does UPD30200GD-80-LBB-A support JTAG debugging?

Yes, UPD30200GD-80-LBB-A includes full IEEE 1149.1 JTAG support via dedicated pins JTCK, JTDI, JTDO, and JTMS. These pins enable boundary-scan testing, device identification, and in-circuit debugging. The JTAG interface remains active regardless of processor state and does not require software initialization - making it essential for hardware validation and field diagnostics of UPD30200GD-80-LBB-A-based systems.

What is the function of the DivMode pins on UPD30200GD-80-LBB-A?

The DivMode(1:0) pins on UPD30200GD-80-LBB-A configure the internal PLL's frequency multiplication ratios between MasterClock, PClock, and TClock. For example, DivMode=10 sets a 1:2:1 ratio (e.g., 40 MHz → 100 MHz → 40 MHz), directly determining system timing budgets. These pins must be held static after power-up; changing them dynamically invalidates guaranteed operation per the datasheet.

How does ColdReset differ from Reset on UPD30200GD-80-LBB-A?

ColdReset performs full hardware initialization of all internal registers and status bits, independent of MasterClock synchronization. Reset, in contrast, triggers a software exception without clearing CPU state - preserving register contents for diagnostic analysis. Both signals are asynchronous, but only ColdReset guarantees deterministic boot behavior for UPD30200GD-80-LBB-A in safety-critical embedded applications.

What package type is used for UPD30200GD-80-LBB-A?

UPD30200GD-80-LBB-A uses a 120-pin plastic QFP package measuring 28 mm × 28 mm with 0.8 mm lead pitch. The "LBB" suffix denotes this specific lead finish and mold compound variant. Mechanical dimensions and soldering profiles are documented in the P120GD-80-LBB package drawing, including recommended reflow peak temperature (235°C) and moisture sensitivity level (MSL 3).
