• Manufacturer Part Number: hd66100
• Description: H8/3867 Series
• Manufacturer: Renesas Electronics Corporation.

11.1
The H8/3864 Series is provided with a 14-bit PWM (pulse width modulator) on-chip, which can
be used as a D/A converter by connecting a low-pass filter.
11.1.1
Features of the 14-bit PWM are as follows.
Any of the following four conversion periods can be chosen:
131,072/ø, with a minimum modulation width of 8/ø (PWCR1 = 1, PWCR0 = 1)
65,536/ø, with a minimum modulation width of 4/ø (PWCR1 = 1, PWCR0 = 0)
32,768/ø, with a minimum modulation width of 2/ø (PWCR1 = 0, PWCR0 = 1)
16,384/ø, with a minimum modulation width of 1/ø (PWCR1 = 0, PWCR0 = 0)
11.1.2
Figure 11.1 shows a block diagram of the 14-bit PWM.
Choice of two conversion periods
Pulse division method for less ripple
Use of module standby mode enables this module to be placed in standby mode independently
when not used.
