Z51F3220 MCU
The Z51F3220 MCU, a member of Zilog’s new Z8051 product family, is an advanced
CMOS 8-bit microcontroller with 32 KB of Flash memory. This powerful microcontroller
provides a highly flexible and cost-effective solution to many embedded control applica-
tions, including motor control. The key features of the Z51F3220 MCU include:
•
16 MHz high-performance 8-bit CISC core
•
Up to 32 KB Flash program memory
•
Highly-integrated digital/analog peripherals:
– 10-bit pulse-width modulator (PWM) module with three complementary pairs of
PWM outputs
– 16-channel 12-bit Analog-to-Digital Converter (ADC) for current sampling and
back-EMF detection
– 16-bit timer with capture, compare, and PWM capability
– Flexible communication interface including a UART, I
2
C, and SPI
– LCD driver (21 segments/8 common)
