FAQ

What is the maximum operating frequency of the HD6417720BP133CV?

The HD6417720BP133CV operates at a maximum clock frequency of 133 MHz, achieved via internal PLL multiplication of an external 1–33 MHz reference clock. This frequency is guaranteed across the commercial temperature range (0°C to +70°C) and 3.3 V ±0.3 V supply, enabling consistent real-time performance in deterministic embedded applications. The HD6417720BP133CV's five-stage pipeline sustains this rate with minimal stall penalties.

Does the HD6417720BP133CV include a Memory Management Unit (MMU)?

Yes, the HD6417720BP133CV integrates a full Memory Management Unit (MMU) with a 64-entry fully associative Translation Lookaside Buffer (TLB). This MMU supports virtual memory mapping, page-level protection, and context switching - essential for running Linux, uClinux, or other protected-mode RTOS environments. The HD6417720BP133CV's MMU implementation complies with SH-3 architecture specifications and is documented in Section 4 of the Hardware Manual Rev.4.00.

What package type and pin count does the HD6417720BP133CV use?

The HD6417720BP133CV uses a 256-pin Low Profile Quad Flat Package (LQFP) with 0.5 mm lead pitch and 28 mm × 28 mm body dimensions. This package includes an exposed thermal pad for enhanced heat dissipation and is fully compatible with standard reflow soldering profiles. Pin assignments match the SH7720 Group standard layout defined in Section 1.3 of the Hardware Manual Rev.4.00.

Which instruction set does the HD6417720BP133CV implement?

The HD6417720BP133CV implements the SH-3 instruction set architecture with SH3-DSP extensions, ensuring binary compatibility with existing SH-3 software and toolchains including compilers, debuggers, and RTOS kernels. It does not support SH-4 or SH-4A instructions. The HD6417720BP133CV's instruction decoder executes all SH-3 integer, control flow, and DSP-enhanced operations as specified in the SH-3/SH-3E/SH3-DSP Software Manual (REJ09B0317).

What are the primary on-chip peripherals integrated into the HD6417720BP133CV?

The HD6417720BP133CV integrates a 4-channel DMAC, two 32-bit Compare Match Timers (CMT), two Serial Communication Interface with FIFO (SCIF) modules, one UART, a Real-Time Clock (RTC), an SDRAM controller, and a Clock Pulse Generator (CPG). These peripherals enable self-contained system designs without external glue logic. All are accessible via memory-mapped registers and support interrupt-driven operation - critical for efficient resource utilization in the HD6417720BP133CV-based systems.
