Overview
The C8051F413-GM is an 8-bit microcontroller from the C8051F41x series, featuring a high-speed 8051 core operating at up to 50 MHz. It integrates 16 kB of in-system programmable Flash memory and 2304 bytes of internal data RAM. The device includes a 12-bit ADC with up to 24 external inputs, two 12-bit current-mode DACs, and two comparators. It operates within a supply voltage range of 2.0 V to 5.25 V and supports temperatures from -40 °C to +85 °C. The component is housed in a 28-pin QFN package.
Feature Summary
- Integrates a smaRTClock real-time clock module with battery-backed RAM for timekeeping during power loss.
- Features a fully pipelined instruction architecture that executes most instructions in one or two system clocks.
- Includes on-chip debug circuitry supporting non-intrusive in-system debugging without requiring external emulators.
Applications
- Data acquisition systems requiring high-resolution analog input processing
- Portable instruments utilizing low-voltage operation and battery backup capabilities
- Industrial control applications needing robust analog peripherals and wide temperature tolerance
Procurement Notes
Verify the specific suffix 'GM' corresponds to the 28-pin QFN package variant. Confirm the device status as Not Recommended for New Designs (NRND) against long-term project requirements. Ensure compatibility with existing firmware architectures designed for the CIP-51 core before initiating procurement.
Selection Notes
Select this model when 16 kB of Flash memory suffices for application code. Choose over the C8051F411 if reduced memory footprint is acceptable. Verify that the 28-pin QFN form factor fits the target PCB layout constraints. Ensure the design accommodates the required analog peripheral count provided by this specific silicon revision.
Part Context
This component belongs to the C8051F41x family of mixed-signal microcontrollers. It shares the same core architecture and peripheral set as the C8051F410, F411, and F412, differing primarily in Flash memory capacity. The family is characterized by its high integration of analog functions within a small form factor.
Replacement Considerations
Public confirmed substitute part numbers: None identified in verified documentation.
FAQ
Does the C8051F413-GM support USB connectivity?
No, the C8051F413 does not include an integrated USB controller. This feature is available in other members of the C8051F4xx family such as the C8051F410.
What is the function of the smaRTClock module?
The smaRTClock provides a real-time clock function with a dedicated 32 kHz oscillator and 64 bytes of battery-backed RAM, allowing timekeeping to continue even when the main power supply is removed.
