HD6417750RF240 - SH7750R 240MHz SuperH RISC MCU | Renesas
MPN: HD6417750RF240 ✓ Hoạt độngHD6417750RF240 Tóm tắt
A microprocessor (MPU) is a VLSI central processing unit on a single chip that integrates the CPU core, caches, MMU, bus interfaces, and peripheral controllers. The SH7750R belongs to the SuperH family: a RISC microprocessor architecture -> 32-bit RISC processor -> embedded microprocessor -> system-on-chip class MPU -> semiconductor IC. This taxonomy situates the HD6417750RF240 within the broader processor hierarchy that scales up to application processors for desktops and down to microcontrollers for deeply embedded sensing.
Key features include a 240 MHz CPU clock with object-code upward compatibility from SH-1, SH-2, and SH-3, 16 KB instruction cache, 32 KB data cache (32 KB unified in SH-4), an integrated MMU with 4-way set-associative TLB, a single-precision IEEE-754 floating-point unit, a 16-bit unified instruction set, and a 32-bit external bus interface supporting SDRAM, SRAM, ROM, and PCMCIA. The 208-pin PQFP (28 mm x 28 mm) package offers a familiar through-hole-style lead footprint suitable for legacy industrial designs and evaluation boards.
The HD6417750R architecture combines a Harvard-style cache hierarchy with a unified external bus, enabling high-throughput data movement for embedded computing workloads such as real-time control, machine vision front-ends, and high-resolution graphical HMI. The integrated FPU and MMU allow full Linux and Windows CE operating-system support, which is rare among 32-bit embedded MPUs of this generation.
Typical applications include industrial machine controllers, factory automation HMIs, in-vehicle infotainment prototypes, network-attached print/image processing engines, point-of-sale terminals, and legacy SH-4 upgrade boards. The 240 MHz performance is well matched to QVGA/VGA-resolution graphics and MPEG-2 decode.
When designing with the HD6417750RF240, pay close attention to the dual-voltage power tree (1.5 V core, 3.3 V I/O), the SDRAM interface timing, and bus-arbiter configuration for any DMAC peripherals. Refer to the Renesas SH7750R hardware manual for PLL loop filter components and reset sequencing.

Ứng dụng tiêu biểu
HD6417750RF240 phù hợp cho 6 Áp dụngs: Industrial Machine Controller HMI, Factory Automation Controller, In-Vehicle Infotainment Prototype, Network Print / Image Processing Engine, Point-of-Sale Terminal, Legacy SH-4 Upgrade Board / Eval Platform.
Industrial Machine Controller HMI
The HD6417750RF240's 240 MHz SH-4 core, integrated FPU, and 32-bit external SDRAM bus make it well-suited to drive QVGA/VGA-resolution HMIs for industrial machine controllers. Placing the MPU between a 3.3 V I/O ring and 1.5 V core rails lets the design run an embedded Linux or Windows CE graphics stack with real-time motion-control threads. The 16 KB instruction cache reduces SDRAM access latency, and the integrated MMU enables full process isolation for safe multi-tasking. Pin compatibility with the same SH-7750R family simplifies panel-meter and operator-interface drop-in upgrades.
Được đề xuất
Factory Automation Controller
In factory automation, the HD6417750RF240 drives fieldbus protocol stacks (PROFIBUS, DeviceNet, EtherCAT slave) over its 32-bit external bus while the integrated FPU accelerates control-loop math. With 48K x 8 of on-chip SRAM it can buffer real-time I/O frames without external scratch memory, and the 240 MHz clock leaves headroom for 1 ms control loops at multi-axis machines. Compared with a microcontroller-class part, the SH-4 MMU enables deterministic Linux with PREEMPT_RT for soft-PLC workloads.
Được đề xuất
In-Vehicle Infotainment Prototype
The HD6417750RF240's integrated IEEE-754 single-precision FPU and MMU let it run a Windows CE or embedded Linux infotainment stack for prototype head units and rear-seat entertainment systems. Its 240 MHz performance handles MP3 decode, JPEG decode, and modest 2D graphics, while the 32-bit SDRAM interface sustains framebuffer throughput for QVGA displays. The legacy PQFP package supports automotive thermal-grade evaluation and the SH-4 ecosystem provides automotive middleware ports.
Được đề xuất
Network Print / Image Processing Engine
Office multifunction printers and document scanners benefit from the HD6417750RF240's 240 MHz SH-4 CPU with hardware FPU for JPEG rasterization, halftoning, and network protocol processing. The 32-bit external bus connects directly to SDRAM for large page buffers, while 16 KB of instruction cache keeps the rendering inner loop resident. The MMU isolates the network stack from the rendering engine, an important security property for connected printers handling untrusted input.
Được đề xuất
Point-of-Sale Terminal
POS terminals need a 32-bit processor that can run a graphical UI, encryption, and a TCP/IP stack concurrently - which is exactly the use case the HD6417750RF240 was designed for. Its integrated FPU accelerates RSA/ECC handshakes for chip-card and contactless readers, and the MMU provides process isolation between the payment application and the merchant UI. The ROMless architecture lets OEMs mask their own secure boot ROM externally.
Được đề xuất
Legacy SH-4 Upgrade Board / Eval Platform
Engineers maintaining installed SH-3 and SH-4 systems use the HD6417750RF240 as a drop-in upgrade to existing 208-PQFP socket boards, gaining 240 MHz performance and the SH-4 MMU/FPU without a PCB redesign. The same SH-4 object-code compatibility means existing firmware and RTOS BSPs recompile cleanly. The 48K x 8 of on-chip SRAM also enlarges the working buffer available to legacy applications.

Ghi chú thiết kế
The HD6417750RF240 requires a dual-voltage power tree: 1.4-1.6 V (typical 1.5 V) on the Vcc pins and 3.0-3.6 V (typical 3.3 V) on the I/O pins. According to the SH7750R hardware manual, the core rail must reach 0.8 V before the I/O rail reaches 2.0 V during power-up to prevent I/O latch-up. Use a power sequencer IC or place a Schottky steering network on the 3.3 V rail. Decouple each Vcc/Vss pair with a 0.1 uF ceramic plus a 10 uF bulk capacitor placed within 5 mm of the pin.
Route the 32-bit external data bus (D[31:0]) and address bus (A[25:0]) as matched-length traces with a 50 ohm characteristic impedance to SDRAM. Keep trace length mismatch below 25 mil between any two data/address lines to avoid double-clocking at 240 MHz internal / 60-120 MHz bus ratios. Place SDRAM termination resistors at the far end of the bus and series-stagger the clock trace to suppress reflections.
Estimated: the 208-PQFP package has a typical theta_JA of approximately 35 C/W on a 4-layer JEDEC test board. At 240 MHz full-load (estimated core current 600 mA at 1.5 V plus 100 mA at 3.3 V I/O), total dissipation is approximately 1.2 W, giving a junction temperature rise of ~42 C above ambient. Provide at least 1 square inch of continuous ground plane under the PQFP for reliable operation above 70 C ambient.
Do not leave the MODE pins (MD0/MD1) floating - they select the boot area and endian mode at the rising edge of RESET. Tie them to Vcc or Vss through 10 kohm resistors. Also confirm that the XTAL/EXTAL pins are routed with a short guard trace to Vss, since noise on the crystal input can corrupt PLL lock and drop the CPU to an undefined clock.
