Renesas QB-32FP-EA-04T

Overview

QB-32FP-EA-04T from Renesas Electronics is a T-type exchange adapter designed for the QB-RL78G1F in-circuit emulator, enabling physical and electrical interface between the emulator and RL78/G1F microcontrollers in 32-pin QFP packages. It supports target system power supply voltages from 1.6 V to 5.5 V, operates within 0–40°C ambient, and enables real-time emulation with up to 512 KB internal ROM and 61.75 KB internal RAM visibility. Used in embedded firmware development for industrial control and automotive body electronics.

For engineers reviewing the QB-32FP-EA-04T datasheet, QB-32FP-EA-04T pinout, QB-32FP-EA-04T application, or QB-32FP-EA-04T equivalent, this page delivers verified mechanical compatibility, target-device-specific signal routing, thermal and voltage interface constraints, and integration guidance with QB-RL78G1F emulator hardware and RL78/G1F-based target systems.

Technical Context

The QB-32FP-EA-04T is a passive mechanical and electrical interface adapter - not an active IC - that routes debug, clock, power, and reset signals between the QB-RL78G1F emulator base unit and RL78/G1F microcontrollers in 32-pin QFP (32FP) packages. It forms part of a multi-component T-type configuration including QB-32FP-NQ-01T (target connector), QB-32FP-YQ-01T (YQ connector), and QB-32FP-YS-01T (space adapter).

It provides direct pin-to-pin mapping for SWD/JTAG debug interface lines (including RESET, CLK, TDI, TDO, TMS), VDD/VSS rails, and oscillator inputs (X1, XT1), preserving signal integrity for real-time trace and memory access at up to 120 MHz measurement clock rate. No onboard logic, voltage translation, or buffering is implemented.

FAQ

Is QB-32FP-EA-04T compatible with any emulator other than QB-RL78G1F?

No. QB-32FP-EA-04T is mechanically and electrically designed exclusively for use with the QB-RL78G1F in-circuit emulator. Its pin layout, signal routing, and mounting interface match only QB-RL78G1F's TCN1/TCN3 connector system and T-type adapter stack. It is not compatible with E1/E20 emulators, IAR KickStart tools, or third-party debug probes.

Does QB-32FP-EA-04T include voltage level translation for RL78/G1F I/O signals?

No. QB-32FP-EA-04T is a passive signal-routing adapter with no active circuitry. It does not translate voltage levels, buffer signals, or condition timing. Target system VDD must fall within QB-RL78G1F's supported 1.6 V–5.5 V range, and all debug interface signals (SWD/JTAG) must operate at the same voltage as the target's VDD rail.

What additional components are required to use QB-32FP-EA-04T with an RL78/G1F target board?

QB-32FP-EA-04T requires three mandatory companion parts: QB-32FP-NQ-01T (soldered target connector), QB-32FP-YQ-01T (YQ mating connector), and QB-RL78G1F emulator base unit. Optional components include QB-32FP-YS-01T (height-adjustable space adapter) and QB-32FP-HQ-01T (mount adapter) if socket-based target mounting is used.

Can QB-32FP-EA-04T support real-time trace functionality of QB-RL78G1F?

Yes. QB-32FP-EA-04T preserves full signal integrity for QB-RL78G1F's trace capabilities - including program address/data, access address/data, status, and time-tagged events - by providing direct, low-capacitance routing of all required debug bus lines. Trace depth remains at 128K frames when used with this adapter.

Is QB-32FP-EA-04T RoHS compliant and lead-free?

Yes. QB-32FP-EA-04T complies with EU RoHS Directive 2011/65/EU and is manufactured using lead-free solder and halogen-free materials. Environmental compliance documentation is available through Renesas Electronics' official product portal and distributor portals such as Digi-Key and Mouser.
