Renesas QB-144FB-HQ-01T

Overview

QB-144FB-HQ-01T from Renesas Electronics is a mount adapter designed for the RL78/F15 144-pin FBGA target device, enabling secure socket-based connection between the QB-RL78F15 in-circuit emulator and the target system. It supports 144-pin fine-pitch ball grid array (FBGA) packages with 0.8 mm pitch, provides mechanical alignment and thermal stability during debug sessions, and is used with the QB-144FB-NQ-01T target connector and QB-144FB-YQ-01T YQ connector in T-type configurations.

For engineers reviewing the QB-144FB-HQ-01T datasheet, QB-144FB-HQ-01T mechanical drawing, QB-144FB-HQ-01T mounting procedure, or QB-144FB-HQ-01T compatibility with RL78/F15 evaluation, this page delivers verified physical interface specifications, system integration requirements, and OEM deployment guidance specific to high-density FBGA emulation setups.

Technical Context

The QB-144FB-HQ-01T is a passive mechanical adapter that interfaces the QB-RL78F15 emulator with 144-pin FBGA-packaged RL78/F15 microcontrollers. It mates directly with the QB-144FB-NQ-01T target connector soldered onto the user's board and accepts the QB-144FB-YQ-01T YQ connector from the emulator side.

It enables zero-insertion-force (ZIF) socket mounting of the RL78/F15 device, preserving pin integrity during repeated debug cycles. The adapter is dimensionally matched to JEDEC MO-275AB standard for 144-pin FBGA (10 mm × 10 mm body, 0.8 mm ball pitch), and requires no power, signal routing, or electrical configuration.

FAQ

What is the primary function of the QB-144FB-HQ-01T in an RL78/F15 debug setup?

The QB-144FB-HQ-01T is a mount adapter that mechanically secures the 144-pin FBGA-packaged RL78/F15 microcontroller into a zero-insertion-force (ZIF) socket, enabling direct, repeatable connection to the QB-RL78F15 in-circuit emulator via the QB-144FB-NQ-01T and QB-144FB-YQ-01T interface chain. It does not perform signal conditioning or power regulation - its sole role is precise mechanical alignment and retention.

Is QB-144FB-HQ-01T compatible with any microcontroller other than the RL78/F15?

No. The QB-144FB-HQ-01T is dimensionally and mechanically engineered exclusively for the RL78/F15 in 144-pin FBGA package (0.8 mm pitch). Its footprint, ball pattern clearance, and socket engagement geometry are not validated for any other device family, including other RL78 variants or third-party MCUs. Using it with non-RL78/F15 devices risks misalignment, solder ball damage, or unreliable contact.

Does QB-144FB-HQ-01T require power, firmware, or configuration?

No. The QB-144FB-HQ-01T is a passive mechanical component with no electrical circuitry, active elements, or programmable logic. It draws no power, contains no firmware, and requires no configuration or calibration. Its operation depends solely on correct mechanical assembly with the QB-144FB-NQ-01T target connector and QB-144FB-YQ-01T YQ connector in a T-type system configuration.

Can QB-144FB-HQ-01T be used with S-type emulation hardware?

No. The QB-144FB-HQ-01T is designated for T-type configurations only, as confirmed by its part number suffix "-01T" and explicit listing in Table 1-3 under "T Type" entries for RL78/F15 144FB. S-type systems use different mechanical interfaces (e.g., QB-48NA-HQ-02S) and are incompatible due to mismatched mounting holes, connector orientation, and probe interface geometry.

What accessories must be used alongside QB-144FB-HQ-01T to complete a functional debug setup?

To complete a functional RL78/F15 debug setup, QB-144FB-HQ-01T must be used with: (1) QB-144FB-NQ-01T (target connector soldered to the user's PCB), (2) QB-144FB-YQ-01T (YQ connector linking to the emulator), and (3) QB-144FB-EA-01T (exchange adapter). All three are listed in Table 1-3 as mandatory co-components - omission of any invalidates mechanical and electrical continuity for the QB-RL78F15 emulator.
