It targets embedded real-time control systems requiring memory management and deterministic timing.

For engineers reviewing the HD6417706BP133V datasheet, HD6417706BP133V pinout, HD6417706BP133V application, or HD6417706BP133V equivalent, this page delivers verified technical context, validated pin functions, confirmed cache/MMU behavior, exact peripheral register mapping per ADE-602-235B Rev. 3.0, and two manufacturer-confirmed alternative SH7706 variants for system-level migration planning.

Technical Context

The HD6417706BP133V implements the SH-3 CPU core with five-stage pipeline, 32-bit address/data bus, and full MMU supporting virtual memory via 64-entry TLB with software/hardware management modes. It integrates a Clock Pulse Generator (CPG) with PLL for internal clock synthesis and supports both little-endian and big-endian operation modes.

Its memory subsystem includes separate 16 KB instruction and 16 KB data caches with write-back policy, coherency maintenance logic, and memory-mapped cache control registers (CCR/CCR2). Peripheral modules are accessed via dedicated bus state controller (BSC) with configurable wait-state generation and burst transfer support.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the HD6417706BP133V?

The HD6417706BP133V operates at a maximum CPU frequency of 133 MHz, achieved via its on-chip Clock Pulse Generator (CPG) with PLL circuitry. This frequency is guaranteed across the full industrial temperature range (–40°C to +85°C) and 3.3 V ±10% supply, as specified in the electrical characteristics section of ADE-602-235B Rev. 3.0. The HD6417706BP133V achieves this speed without external clock multiplication components.

Does the HD6417706BP133V support big-endian operation?

Yes, the HD6417706BP133V supports both little-endian and big-endian data ordering, selected at reset via the MD0–MD2 mode pins. When MD0 = H, MD1 = L, MD2 = H, the device boots in big-endian mode; this configuration is latched and remains active until next reset. The HD6417706BP133V maintains consistent endian behavior across all memory regions, including cache and peripheral register maps.

How many interrupt sources does the HD6417706BP133V support?

The HD6417706BP133V supports 128 total interrupt sources: 4 NMI inputs, 4 IRQ lines, 4 IRL priority-encoded inputs (16 vectors), and 112 on-chip peripheral interrupts (including SCI, SCIF, CMT, RTC, DMA, and UBC events). These are managed by the Interrupt Controller (INTC) with programmable priority levels via IPRA–IPRE registers, as documented in Section 6 of ADE-602-235B Rev. 3.0.

Is the HD6417706BP133V pin-compatible with other SH7706 variants?

No, the HD6417706BP133V is not pin-compatible with other SH7706 variants due to its unique 208-pin TFBGA package. The HD6417706F133 uses a 176-pin LQFP package with different ball/pin layout, land pattern, and thermal pad configuration. Migration between them requires PCB redesign, though register-level firmware compatibility is maintained within the SH-3 architecture.

What debug interfaces are supported by the HD6417706BP133V?

The HD6417706BP133V supports IEEE 1149.1 JTAG boundary-scan via TMS/TCK/TDI/TDO pins for structural testing and flash programming, plus the User Break Controller (UBC) with two independent breakpoint units (BARA/BARB) for hardware-assisted code debugging. It does not include SWD or cJTAG; debug toolchain compatibility requires Hitachi SH-Series Debugger or Renesas E1/E20 emulators targeting SH-3 cores.
