Overview
1. Overview
Introduction
Zilog’s Z32F3841 MCU, a member of the ZNEO32! Family of microcontrollers, is a cost-effective and highperformance 32-bit microcontroller. The Z32F3841 MCU provides 3-phase PWM generator units which are suitable for inverter bridges, including motor drive systems. Two built-in channels of these generators control two inverter bridges simultaneously.
Two 12-bit high speed ADC units with 16-channel analog multiplexed inputs support feedback retrieval from the inverter bridge. The Z32F3841 MCU can control up to two inverter motors or one inverter motor and the Power Factor Correction (PFC) function simultaneously.
Figure 1.1 shows a block diagram of the Z32F3841 MCU.
