Z16FMC64AG20SG

Overview

The Z16FMC64AG20SG is a 16-bit microcontroller from the Z16FMC series, utilizing the ZNEO core. It features 64 kB of Flash program memory and operates at a maximum clock frequency of 20 MHz. The device provides 46 I/O lines and supports power supply voltages between 2.7 V and 3.6 V. It includes integrated interfaces such as UART, SPI, and I2C, along with a 10-bit ADC. Packaged in a 64-LQFP format, it is designed for surface mount installation within an operating temperature range of 0°C to +70°C.

Feature Summary

• ZNEO 16-bit single-cycle CISC core architecture
• 64 kB Flash program memory with 2K RAM
• Integrated motor control peripherals including PWM channels
• Multiple communication interfaces: UART, SPI, I2C

Applications

• Brushed DC motor control systems
• Blower fan speed regulation
• Pump control applications
• General-purpose industrial automation controllers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity labeling prior to handling. Ensure storage conditions meet specified humidity requirements to prevent package damage during assembly processes.

Selection Notes

Select this model when 64 kB of code space is required for complex motor control algorithms. Compare against Z16FMC32AG20SG if lower memory capacity suffices. Verify that the LQFP-64 package fits the PCB footprint constraints and that the 20 MHz performance meets timing requirements for the specific application load.

Part Context

This component belongs to the Zilog Z16FMC family, specialized for motor control applications. It shares architectural similarities with other Z16F series MCUs but includes dedicated hardware accelerators for PWM generation and current sensing integration, distinguishing it from general-purpose variants like the Z16F3211FI20SG.

Replacement Considerations

Direct pin-compatible substitutes may include other members of the Z16FMC series with different memory sizes, such as Z16FMC32AG20SG or Z16FMC28AG20EG, provided software compatibility is maintained. Cross-family replacements require careful verification of peripheral register mappings.
