Product details
Overview
M30843FWGP#U3 from Renesas Electronics is a 100-pin LQFP Flash-based 16/32-bit microcontroller in the M32C/84 Group, featuring a M32C/80-series CPU core, 320 KB on-chip Flash memory, 10-bit A/D converter with 26 input channels, one CAN 2.0B module, and five serial I/O channels including IEBus and I²C. It operates at up to 32 MHz (31.3 ns instruction cycle) across –20°C to +85°C for industrial control and embedded automation.
For engineers reviewing the M30843FWGP#U3 datasheet, M30843FWGP#U3 pinout, M30843FWGP#U3 application, or M30843FWGP#U3 equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options - all grounded in Renesas' official documentation for the M32C/84 Group (Rev.1.21, Jul. 2005).
Technical Context
The M30843FWGP#U3 implements a 16/32-bit hybrid architecture with dual-voltage operation (VCC1 = 4.2–5.5 V, VCC2 = 3.0–VCC1), integrated PLL frequency synthesizer, and four DMAC channels supporting immediate, calculation, and chain transfer modes. Its intelligent I/O supports time measurement and waveform generation across eight 16-bit channels.
It integrates a 15-bit watchdog timer with prescaler, CRC-CCITT calculation circuit, X/Y 16×16-bit multiplier, and three-phase motor control logic - all coordinated via a 7-level interrupt priority system with 38 internal and 8 external sources.

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 RX66T core, 120 MHz, 512 KB Flash, integrated FPU, no IEBus, added EtherCAT slave support. | Targets higher-performance servo drives requiring floating-point math and industrial Ethernet - not drop-in compatible. | Select when migrating from M32C legacy to modern RX platform with safety certification (IEC 61508 SIL2). |
| M30624FGFP#U3 | M16C/62 Group, 16-bit only, 128 KB Flash, 100-pin LQFP, no CAN, 16-channel A/D, same IEBus/I²C set. | Suitable for cost-sensitive non-networked controls (e.g., printer paper feed) where CAN is unnecessary. | Choose for simpler, lower-cost replacement where CAN and 26-channel A/D are not required. |
Compared with M30843FWGP#U3, R5F566TEADFP#30 offers 3.75× higher CPU throughput and functional safety features but requires board redesign; M30624FGFP#U3 retains pinout compatibility and IEBus support while omitting CAN and reducing A/D channels - making it viable only for non-networked legacy upgrades.

FAQ
What is the maximum operating frequency of the M30843FWGP#U3?
The M30843FWGP#U3 achieves a shortest instruction execution time of 31.3 ns at 32 MHz BCLK with VCC1 = 4.2–5.5 V. At 24 MHz, execution time extends to 41.7 ns under wider voltage range (3.0–5.5 V). This frequency is enforced by the on-chip PLL and clock generation circuit - no external clock multiplier is needed. The M30843FWGP#U3 does not support overclocking beyond 32 MHz.
Does the M30843FWGP#U3 include an integrated CAN transceiver?
No, the M30843FWGP#U3 provides only the CAN protocol controller (CAN 2.0B compliant) with dedicated CAN0IN and CAN0OUT pins. An external CAN physical-layer transceiver (e.g., TJA1042, SN65HVD230) must be used to drive the differential bus. The M30843FWGP#U3 itself handles message filtering, arbitration, and error handling - but not voltage level translation or bus termination.
How many analog input channels does the M30843FWGP#U3 support?
The M30843FWGP#U3 supports 26 analog input channels in its 100-pin LQFP configuration, as confirmed in Table 1.2 of the official datasheet (Rev.1.21). These map to pins P00–P07, P100–P107, and P94–P97 (ANEX0/ANEX1). This is fewer than the 34-channel capability of the 144-pin variant, due to package pin count limitations - not a firmware or silicon revision difference.
Is the M30843FWGP#U3 RoHS compliant?
Yes, the M30843FWGP#U3 meets EU RoHS Directive requirements, as confirmed by Renesas' environmental compliance documentation. It contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits. Lead-free soldering profiles (per J-STD-020) apply - peak reflow temperature must not exceed 260°C for 10 seconds. The M30843FWGP#U3 is marked with RoHS-compliant packaging codes per Renesas' material declaration.
What development tools support the M30843FWGP#U3?
Renesas provides full toolchain support for the M30843FWGP#U3 via the CS+ (formerly High-performance Embedded Workshop) IDE, C compiler (M32C/80 family), and E8/E8a debug emulators. Third-party options include IAR Embedded Workbench for M32C and PEEDI JTAG adapters. The M30843FWGP#U3 is also supported by Renesas' official evaluation board EK-M32C/84, which includes on-board CAN transceivers, IEBus connectors, and A/D test points.
