Product details
Overview
M3087BFKBGP#U3P from Renesas Electronics is a 144-pin LQFP microcontroller in the M32C/87B group, featuring the M32C/80 CPU core, 768 KB + 4 KB data flash, 48 KB RAM, CAN 2.0B support disabled, and operation up to 32 MHz at 4.2–5.5 V. It targets industrial motor control and office automation systems requiring integrated PWM, 3-phase inverter timing, and multi-protocol serial interfaces.
For engineers reviewing the M3087BFKBGP#U3P datasheet, M3087BFKBGP#U3P pinout, M3087BFKBGP#U3P application, or M3087BFKBGP#U3P equivalent, key selection criteria include its 144-pin PLQP0144KA-A package, absence of CAN modules, 34-channel 10-bit ADC (single-chip mode), dual 8-bit DACs, and on-chip dead-time timer for motor gate drive coordination.
Technical Context
The M3087BFKBGP#U3P implements the M32C/80 16-bit CPU core with 108 basic instructions and hardware multiplier supporting 16×16→32-bit multiply-add operations. Its memory architecture includes 768 KB main flash plus 4 KB dedicated data flash, enabling field reprogramming and parameter storage without external EEPROM.
Peripheral integration centers on real-time control: five 16-bit Timer A units (with PWM, encoder input, and one-shot modes) and six 16-bit Timer B units (for pulse width/period measurement), coordinated via an on-chip dead-time timer for 3-phase inverter gate driving. Serial connectivity comprises seven UART channels (including IrDA and I²C-compatible modes), but no CAN functionality per M32C/87B specification.

FAQ
Does M3087BFKBGP#U3P include CAN interface functionality?
No. The M3087BFKBGP#U3P belongs to the M32C/87B subgroup, which explicitly omits CAN modules per Renesas documentation (REJ03B0127-0151 Table 1.7). Pins labeled CAN0IN/CAN0OUT and CAN1IN/CAN1OUT are present but non-functional; they may be repurposed as general I/O or UART signals. For CAN-enabled variants, consider M3087BFLGP (M32C/87) or M3087BFKAGP (M32C/87A).
What is the maximum ADC channel count supported by M3087BFKBGP#U3P?
The M3087BFKBGP#U3P supports 34 channels of 10-bit analog-to-digital conversion in single-chip mode, as confirmed in Table 1.1 of the Renesas datasheet REJ03B0127-0151. This count drops to 26 channels in memory expansion or microprocessor modes due to pin multiplexing with address/data bus lines.
Which package type does M3087BFKBGP#U3P use?
M3087BFKBGP#U3P uses the 144-pin LQFP package designated PLQP0144KA-A (20 mm × 20 mm, 0.5 mm pitch), verified in Table 1.7 and Figure 1.1 of the Renesas M32C/87 Group datasheet REJ03B0127-0151. This package provides full access to all 144 pins, including Ports P11–P15 and the complete 34-channel ADC.
Can M3087BFKBGP#U3P operate at 3.3 V supply voltage?
Yes, M3087BFKBGP#U3P supports 24 MHz operation at VCC1 = 3.0–5.5 V and VCC2 = 3.0 V to VCC1, per Table 1.1 and Table 1.3. At 3.3 V, typical current consumption is 23 mA (active), 45 μA (wait mode), and 0.8 μA (stop mode), enabling compatibility with standard 3.3 V system rails.
What debug and programming interfaces are available on M3087BFKBGP#U3P?
M3087BFKBGP#U3P features on-chip debug capability and on-board flash reprogramming via the standard Renesas E8/E8a emulator interface. No external debug probe is required for firmware development or field updates, and ROM code protection with ID code check ensures secure programming.
