Product details
Overview
M30800SAFP#U3 from Renesas Electronics is a ROMless, 100-pin LQFP single-chip 16/32-bit microcontroller based on the M32C/80 series CPU core, operating at up to 32 MHz (31.3 ns min instruction time), featuring 47 I/O pins, 10-bit A/D converter with 10 channels, dual 8-bit D/A outputs, and 4-channel DMAC - deployed in office automation equipment, industrial motor control systems, and communication devices.
For engineers reviewing the M30800SAFP#U3 datasheet, M30800SAFP#U3 pinout, M30800SAFP#U3 application, or M30800SAFP#U3 equivalent, key selection considerations include its microprocessor-mode boot behavior, 16-Mbyte address space, integrated PLL frequency synthesizer, three-phase motor control circuit, and support for IEBus, I²C, and five UART/serial I/O channels.
Technical Context
The M30800SAFP#U3 implements the M32C/80 CPU core with dual register banks, 24-bit addressing capability, and hardware multiplier for high-speed arithmetic. It supports three operating modes: single-chip, memory expansion, and microprocessor mode - the latter activated after reset, requiring external memory interface configuration via 16-bit multiplexed or separate bus control.
Its peripheral subsystem integrates five independent serial I/O channels (supporting clock-synchronous/asynchronous, IEBus v1, and I²C), a 15-bit watchdog timer with prescaler, CRC-CCITT calculation circuit, and intelligent I/O communication function with two dedicated channels - all managed through a unified interrupt controller supporting 34 internal + 8 external sources and 7 priority levels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F566TEADFP#30 | 32-bit RXv2 core, 128 KB flash, 20 KB RAM, 100-pin LQFP; includes CAN FD, USB, and enhanced security | Targets automotive body control and industrial gateways requiring functional safety (IEC 61508 SIL2) | Select when flash-based firmware updates, CAN connectivity, or higher interrupt throughput are required - not ROMless or IEBus-compatible |
| M30624FGFP#U3 | M16C/60 family, 100-pin LQFP, 256 KB flash, 12 KB RAM; same pin count but different peripheral set and no IEBus | Suitable for general-purpose industrial HMI where ROMless boot and legacy IEBus are unnecessary | Choose for cost-sensitive designs needing integrated flash and simpler toolchain - lacks three-phase motor control and intelligent I/O features |
Compared with M30800SAFP#U3, R5F566TEADFP#30 offers modern architecture and safety features but requires full firmware rework and lacks IEBus; M30624FGFP#U3 provides flash convenience but omits critical motor control and intelligent I/O hardware - making M30800SAFP#U3 uniquely suited for legacy IEBus-based office equipment and precision motor systems.

FAQ
What boot mode does the M30800SAFP#U3 enter after power-on reset?
The M30800SAFP#U3 enters microprocessor mode after reset, requiring external program memory (ROM/Flash) and proper bus configuration (BYTE, CS, RD, WR signals) before executing code. This behavior is fixed and cannot be altered via configuration bits since the device is ROMless and lacks on-chip boot ROM.
Does the M30800SAFP#U3 support I²C multi-master operation?
Yes, the M30800SAFP#U3 supports I²C multi-master operation on its two dedicated I²C channels (SCL0/SDA0 and SCL1/SDA1). Each channel implements full arbitration, clock stretching, and 7-bit/10-bit addressing per I²C specification - confirmed in Section 1.2 and Table 1.1 of the REJ03B0038-0110 datasheet.
What is the function of the ANEX0 and ANEX1 pins on the M30800SAFP#U3?
ANEX0 (P95) and ANEX1 (P96) serve as extended analog inputs for the 10-bit A/D converter, enabling two additional channels beyond the standard AN0–AN7. They also support external op-amp connection mode for differential or rail-to-rail analog signal conditioning - documented in Table 1.4 and Figure 1.1 block diagram.
Can the M30800SAFP#U3 generate PWM waveforms for three-phase motor control without CPU intervention?
Yes, the M30800SAFP#U3 includes a dedicated three-phase motor control circuit that generates complementary PWM outputs with programmable dead-time insertion and fault protection - fully hardware-managed and independent of CPU execution, as specified in Section 1.2 "Peripheral I/O Port" and Figure 1.1.
Is the M30800SAFP#U3 RoHS compliant and halogen-free?
Yes, the M30800SAFP#U3 meets EU RoHS Directive requirements and is halogen-free, consistent with Renesas Electronics' environmental compliance policy stated in Section 10 of the REJ03B0038-0110 document and confirmed on the official Renesas product page for the M32C/80 Group.
