Overview
The MC9S08AC48CFDE is an 8-bit microcontroller from the S08AC series, featuring a 40 MHz S08 core. It integrates 48 kB of Flash program memory and 2 kB of RAM. The device operates within a voltage range of 2.7 V to 5.5 V and supports a maximum clock frequency of 40 MHz. It includes an 8-channel, 10-bit ADC and offers 38 programmable I/O lines. Communication interfaces include I2C, SCI, and SPI. The component is housed in a 48-pin QFN package with an exposed pad.
Feature Summary
- Integrates high-capacity non-volatile Flash memory for complex application storage
- Provides multiple serial communication protocols for system connectivity
- Includes analog-to-digital conversion capabilities for sensor interfacing
Applications
- General-purpose embedded control systems
- Industrial automation controllers
- Consumer electronics devices requiring serial communication
Procurement Notes
Verify the specific suffix CFDE to confirm the QFN-48 package type and commercial temperature range. Ensure compatibility with existing PCB footprints, as this variant differs from MF or MP package options within the same family. Confirm RoHS compliance status through official manufacturer documentation prior to integration.
Selection Notes
Select this model when 48 kB of program memory is required alongside standard 8-bit processing performance. The S08AC series provides enhanced peripheral sets compared to basic S08 variants. Consider the 40 MHz operating speed and available I/O count against project requirements before choosing alternative memory sizes in the AC series lineup.
Part Context
This component belongs to the NXP Flexis AC series of 8-bit microcontrollers. It shares the S08 core architecture with other models like the MC9S08AC32 and MC9S08AC60. The AC series is designed for cost-sensitive applications requiring reliable performance and integrated peripherals without the complexity of higher-end architectures.
Replacement Considerations
MC9S08AC32CFDE: Offers reduced memory capacity (32 kB Flash) but maintains identical pinout and core specifications. MC9S08AC60CFDE: Provides increased memory (60 kB Flash) while retaining the same package and peripheral configuration.
