PIC16C77T-04E/L

Microcontrollers Overview

The PIC16C77T-04E/L is a microcontroller component supported by the MPLAB ICE 2000 emulation system via specific processor modules. The emulator system utilizes interchangeable processor modules and device adapters to interface with target applications. Operating voltage for the emulator processor can be supplied by the pod at +5V or by the target application between 2.0V and 5.5V. Standard voltage operation occurs between 4.55V and 5.5V, while low voltage operation ranges from 2.0V to 4.55V. The system supports internal clocking from the emulator pod or external clocking from the target board.

Microcontrollers Feature Summary

• Interchangeable processor module architecture allows configuration for different PICmicro MCU families within the MPLAB ICE 2000 system.
• Supports both internal clocking from the emulator pod and external clocking from the target application oscillator circuit.
• Provides configurable power supply options, allowing the emulator processor to be powered by the emulator pod or the target application system.
• Includes freeze mode functionality to halt peripheral operation when the processor is halted, excluding specific older processor modules.

Microcontrollers Applications

• Emulation of PIC16C77 microcontrollers using the MPLAB ICE 2000 system
• Development and debugging of target application systems requiring precise oscillator characteristic matching
• Low-voltage embedded control system prototyping with voltage levels between 2.0V and 5.5V

Microcontrollers Procurement Notes

Verify that the specific processor module compatible with the PIC16C77 family is available for the MPLAB ICE 2000 system. Confirm the required device adapter matches the package type of the target hardware. Ensure the host PC has an available parallel port or appropriate interface card for the host-to-pod cable connection. Check for any software limitations regarding code protection or EEPROM emulation in the MPLAB IDE settings.

Microcontrollers Selection Notes

Select this component for development environments utilizing the MPLAB ICE 2000 emulator. Ensure the target application voltage falls within the supported range of 2.0V to 5.5V. Consider the need for transition sockets if the target device uses surface mount packages not directly supported by standard device adapters. Verify compatibility with the specific processor module assigned to the PIC16C77 family.

Microcontrollers Part Context

This part number represents a specific variant of the PIC16C77 microcontroller series. It is designed for use with Microchip's MPLAB ICE 2000 in-circuit emulator system. The 'T' suffix typically indicates a tape and reel packaging option, while '04E' denotes the speed grade and temperature range. The 'L' suffix often refers to the plastic package type. This component serves as the target device for emulation rather than the emulator hardware itself.

Microcontrollers Replacement Considerations

No public confirmed substitute part numbers are documented in the provided source material. Compatibility depends on the availability of the correct processor module for the MPLAB ICE 2000 system.

Microcontrollers FAQ

How is the operating voltage configured for the processor module?

The operating voltage is software selectable through the MPLAB IDE. It can be powered by the emulator pod at +5V or by the target application system between 2.0V and 5.5V.

What are the clock source options for the emulator?

The MPLAB ICE 2000 allows internal clocking from the emulator pod's programmable clock or external clocking from the target application's oscillator circuit.

Does the processor module support freeze mode?

Freeze mode is available on most processor modules, allowing peripherals to continue operating while the processor is halted. However, it is not available on the PCM16XA0 module.
