FAQ

What is the maximum operating frequency and supply voltage range for the M30876FJAGP#U3?

The M30876FJAGP#U3 operates up to 32 MHz at VCC1 = 4.2–5.5 V, or up to 24 MHz at VCC1 = 3.0–5.5 V. VCC2 must be within 3.0 V to VCC1. These ranges are defined in Renesas document REJ03B0127-0151 Rev.1.51, Table 1.4, and govern stable execution timing and flash programming voltage compliance for the M30876FJAGP#U3.

Does the M30876FJAGP#U3 support both CAN 2.0A and CAN 2.0B protocols?

Yes, the M30876FJAGP#U3 supports CAN 2.0B specification exclusively - including extended identifier frames (29-bit) and standard frames (11-bit). It does not implement CAN 2.0A-only mode. The dual CAN modules (CAN0 and CAN1) each provide full 2.0B functionality with 16-message slot buffers, as confirmed in Table 1.4 and Section 1.1.2 of the M30876FJAGP#U3 datasheet.

How many A/D converter channels are available on the M30876FJAGP#U3 in single-chip mode?

In single-chip mode, the M30876FJAGP#U3 provides 26 channels of 10-bit A/D conversion with sample-and-hold. This is explicitly stated in Table 1.4 (Specifications, 100-Pin Package) of the official Renesas datasheet REJ03B0127-0151 Rev.1.51, and applies directly to the M30876FJAGP#U3 variant.

What debug and programming interfaces does the M30876FJAGP#U3 support?

The M30876FJAGP#U3 supports on-chip debug via dedicated debug interface pins and on-board flash reprogramming at 3.3 V ±0.3 V or 5.0 V ±0.5 V. It includes ROM code protection and ID code check security features. These capabilities are documented in Table 1.4 and Section 1.1.2 of the Renesas M32C/87 Group datasheet (REJ03B0127-0151 Rev.1.51) for the M30876FJAGP#U3.

Is the M30876FJAGP#U3 qualified for industrial temperature range operation?

Yes, the M30876FJAGP#U3 is rated for −20°C to +85°C operating ambient temperature, as specified in Table 1.4 of the Renesas M32C/87 Group datasheet (REJ03B0127-0151 Rev.1.51). This qualifies it for standard industrial applications without requiring extended temperature grade screening.
