MC68711E20CFNE4 FAQs

1.Q: What are related parts to the NXP 68HC11 for upgrades?

A: Consider NXP’s 16-bit HC12 or modern 32-bit Kinetis/KE series for higher performance, though pin compatibility may vary.

2.Q: Is the NXP 68HC11 RoHS compliant?

A: Yes, it is RoHS compliant but marked as obsolete. Check NXP’s website for replacement options.

3.Q: What is the thermal resistance of the NXP 68HC11 in PLCC-52?

A: Not explicitly stated in the provided data, but PLCC packages typically have θJA (junction-to-ambient) around 30–50°C/W. Verify with thermal testing.

4.Q: Does the NXP 68HC11 support communication interfaces other than SPI/SCI?

A: No. It only includes SPI (1 channel) and SCI (serial UART-like interface). No I2C, USB, CAN, or Ethernet support.

5.Q: What applications is the NXP 68HC11 microcontroller suitable for?

A: Ideal for industrial control, automotive systems (non-PPAP), embedded systems, and legacy designs requiring 8-bit processing with EEPROM/OTP memory.

6.Q: What are the recommended operating conditions for the NXP 68HC11?

A: It operates at 4.5V–5.5V, 4MHz clock, -40°C to +85°C, with typical 5V supply. Ensure power dissipation stays below 195mW.

7.Q: What is the pinout configuration of the NXP 68HC11 in PLCC-52 package?

A: The PLCC-52 package has J-lead pins arranged around a 19.1x19.1mm body, including 38 I/O pins, power (VDD/GND), ADC inputs, SPI/SCI pins, and timer/reset controls. Refer to the datasheet for the exact pinout diagram.

8.Q: What are the key features of the NXP 68HC11 microcontroller?

A: The 68HC11 features an 8-bit CISC core, 20KB OTP program memory, 768B RAM, 512B EEPROM, 38 I/O pins, 8-channel 8-bit ADC, SPI/SCI interfaces, and operates at 4MHz with 5V supply.
