ST72F561J9TA

Microcontrollers Overview

The ST72F561J9TA is an 8-bit microcontroller from the ST7 series, manufactured by STMicroelectronics. It features a 60KB (60K x 8) Flash program memory and 2K x 8 RAM. The device operates at a maximum speed of 8MHz with an external oscillator and supports a supply voltage range of 3.8V to 5.5V. It includes six 10-bit analog-to-digital converters and provides 24 I/O lines. The component is housed in a 44-LQFP surface-mount package and is rated for operation between -40°C and 125°C.

Microcontrollers Feature Summary

• Integrated CANbus, LIN, SCI, and SPI communication interfaces for versatile connectivity.
• Includes hardware peripherals such as LVD, POR, PWM, and WDT for system reliability.
• Features six 10-bit A/D channels for analog signal processing.

Microcontrollers Applications

• Automotive electronic control units requiring CAN/LIN support
• Industrial controllers utilizing PWM and watchdog timers
• Embedded systems needing robust analog input via ADC

Microcontrollers Procurement Notes

Verify the specific package variant, as the J9 suffix typically denotes a 44-pin LQFP configuration distinct from other pin counts in the same family. Confirm RoHS compliance status and check for end-of-life notifications, as availability may be limited due to production status changes. Ensure the selected revision matches the required operating temperature range and interface specifications for your design.

Microcontrollers Selection Notes

Select this component when an 8-bit architecture with integrated automotive-grade communication buses is required. It is suitable for designs needing moderate code storage capacity and multiple analog inputs without external converters. Consider the 44-pin footprint constraints and verify that the external clock requirement aligns with your system's timing resources.

Microcontrollers Part Context

This part belongs to the ST72F family of 8-bit microcontrollers designed for cost-sensitive applications. It shares the core ST7 processor architecture with other variants like the ST72F561K9T3, differing primarily in package type and pin count. The family is known for integrating essential peripherals directly onto the die to reduce external component count.

Microcontrollers Replacement Considerations

Direct substitutes include other ST72F561 variants with compatible pinouts, such as the ST72F561K9T3 if the package difference is acceptable. Cross-referencing with newer STMicroelectronics 8-bit families may require significant schematic and firmware redesign due to architectural differences.
