NXP MCHC11F1CFNE4

MCHC11F1CFNE4 Allgemeine Beschreibung

The MC68HC11F1 microcontroller unit (MCU) is an enhanced member of the M68HC11 family of microcontrollers and offers a range of advanced features.

Funktionen

M68HC11 Central Processing Unit (CPU): The MCU features the M68HC11 CPU core, which serves as the central processing unit responsible for executing instructions and controlling the device's operation.

Power Saving Modes: It supports power-saving modes like STOP and WAIT, which help reduce power consumption during idle or low-activity periods.

512 Bytes EEPROM: The MCU includes 512 bytes of Electrically Erasable Programmable Read-Only Memory (EEPROM), which can be used for storing data that needs to be retained even when power is disconnected.

1024 Bytes RAM: It has 1024 bytes of RAM (Random Access Memory), and this RAM retains data even during standby or low-power modes.

Nonmultiplexed Address and Data Buses: The MCU uses nonmultiplexed address and data buses, simplifying interfacing with external memory and peripherals.

Enhanced 16-Bit Timer: This microcontroller features an enhanced 16-bit timer, which can be used for various timing and control applications.

Input Capture (IC) Channels: It includes three Input Capture (IC) channels for capturing external events or signals.

Output Compare (OC) Channels: Four Output Compare (OC) channels are available for generating output signals or triggering events based on comparisons.

Additional Channel: There is one additional channel that can be configured as either the fourth Input Capture (IC) or the fifth Output Compare (OC) channel.

8-Bit Pulse Accumulator: The MCU has an 8-bit pulse accumulator for counting pulses or events.

Real-Time Interrupt Circuit: It features a real-time interrupt circuit, which can be used for time-critical tasks and event handling.

Computer Operating Properly (COP) Watchdog: The MCU includes a watchdog timer (COP) to monitor and reset the device in case of software or hardware failures.

Enhanced Serial Communication Interfaces: It supports an enhanced Asynchronous Nonreturn to Zero (NRZ) Serial Communications Interface (SCI) and an Enhanced Synchronous Serial Peripheral Interface (SPI) for serial communication with other devices.

Eight-Channel 8-Bit Analog-to-Digital Converter (A/D): The MCU includes an eight-channel 8-bit A/D converter for analog signal measurement and conversion.

Chip-Select Signal Outputs: It provides four chip-select signal outputs with programmable clock stretching, including two I/O chip selects, one program chip select, and one general-purpose chip select.

Package Options: The MCU is available in 68-Pin Plastic Leaded Chip Carrier (PLCC) and 80-Pin Plastic Quad Flat Pack (QFP) package options.
