MKM33Z64ACLL5R

Microcontrollers Overview

The MKM33Z64ACLL5R is a 32-bit microcontroller from the NXP Kinetis KM family, featuring an ARM Cortex-M0+ core operating at up to 50 MHz. It integrates 64 KB of program flash memory and 16 KB of single-access RAM within a 100-pin LQFP package. The device supports a supply voltage range of 1.71 V to 3.6 V without Analog Front End usage. Key peripherals include a 16-bit SAR ADC, a 24-bit Sigma-Delta AFE with PGA, two I2C modules, two SPI modules, and four UARTs.

Microcontrollers Feature Summary

• Integrates a 16-bit SAR ADC and a 24-bit Analog Front End with programmable gain amplifier for high-precision signal acquisition.
• Includes a segment LCD controller supporting multiple frontplanes and backplanes for direct display driving.
• Features hardware security modules including a CRC module, hardware random-number generator, and unique chip identification.
• Provides multiple low-power modes optimized for power consumption across various operational states.

Microcontrollers Applications

• Smart metering systems requiring precise analog measurements
• Industrial control applications with LCD interface requirements
• Battery-powered devices utilizing low-leakage stop modes
• General-purpose embedded control with isolated communication interfaces

Microcontrollers Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration as defined in the part numbering format. Confirm that the 'AC' designation corresponds to the correct silicon revision and feature set for the intended application. Ensure compatibility with the 100-pin LQFP footprint during PCB layout. Check current availability status as this component may be subject to lifecycle changes.

Microcontrollers Selection Notes

Select this model when 64 KB of flash is sufficient for application code and 16 KB RAM meets data storage needs. Choose this variant over the 128 KB version if cost or pin count optimization is required. Ensure the 100-pin package accommodates all necessary GPIO and peripheral connections. Verify that the 50 MHz maximum frequency aligns with real-time processing requirements.

Microcontrollers Part Context

This component belongs to the Kinetis KM family, designed specifically for metering and industrial applications. It shares architectural similarities with other KM series devices but offers distinct memory and peripheral configurations. The KM family emphasizes low power consumption and robust analog capabilities suitable for utility and sensing environments.

Microcontrollers Replacement Considerations

Direct substitutes within the same package and pinout include MKM33Z64ACLH5 (different package) or MKM33Z128ACLL5 (increased memory). Cross-family replacements require careful peripheral mapping verification. No other NXP models share identical pinouts and specifications simultaneously.
