Overview

The MCF51QM128VHS is a highly-integrated family of mixed-signal microcontrollers based on a ColdFire® V1 core featuring a 16-bit Harvard architecture. The core, combined with 16 kB of on-board flash and 1 kB of SRAM, provides a platform that satisfies robust needs of embedded applications. The MCF51QM128VHS family offers a variety of features, such as a USB 2.0 Full-Speed On-The-Go port, CAN interface, LCD controller, and general-purpose timer module, all of which are integrated into the MCF51QM128VHS in order to reduce board space and cost.

Architecture

The MCF51QM128VHSfamily operatesat up to 60 MHz and offers a rich set of peripherals to provide a complete system solution.

At the heart of the MCF51QM128VHS is aColdFire®V1 core featuring a 16-bitHarvard architecture. The coreoperatesat clock speeds up to 60 MHz, and is designed for low-power operation. The core comes with 16 kB of on-board flash memory as well as 1 kB of SRAM. This combinationmakes the MCF51QM128VHS capable of executing code quickly, with minimal power consumption.

The MCF51QM128VHS features a wide array of on-chip peripherals, such as a USB 2.0 Full-Speed On-The-Go port, a CAN interface, and an LCD controller. These peripherals arehighly integrated into the MCF51QM128VHS, allowing for a compact design with fewer components.

USB 2.0 Full-Speed On-The-Go port

The MCF51QM128VHSfeatures a USB 2.0 Full-Speed On-The-Go port, allowing for the wireless connection of peripherals such as keyboards, mice, and other accessories. The port supports up to twelve endpoints, five bulk endpoints, two isochronous endpoints, and one control endpoint.

The USB 2.0 Full-Speed On-The-Go port provides plug-and-play connectivity, allowing for quick and easy connection of peripheral accessories. Additionally, the port supports a variety of transfer modes such as interrupt, bulk, and isochronous transfers.

CAN interface

The MCF51QM128VHS also features a CAN interface, allowing for the communication of data between devices over a Controller Area Network (CAN). The CAN interface provides an efficient, cost-effective way to communicate data between embedded systems.

The CAN interface supports the CanOpen and DeviceNet protocols, allowing the MCF51QM128VHS to be easily integrated into a system using these protocols. Additionally, the CAN interface supports bus access arbitration, which allows for multiple devices to share a single bus without conflict.

LCD controller

The MCF51QM128VHS features an LCD controller, which allows for the easy integration of LCD displays into embedded systems. The LCD controller supports displays with resolutions up to 480 x 320 pixels, with up to sixteen levels of grayscale.

The LCD controller supports an array of interfaces, allowing for a wide range of LCD displays to be easily connected. It supports up to four-bit LCDs, as well as 6- and 8-bit LCDs. Additionally, the LCD controller supports a variety of common parallel interfaces, such as 8-, 9-, 16-, and 18-bit.

General-purpose timer module

The MCF51QM128VHS also features a general-purpose timer module, which can be used for various timing purposes in embedded systems. The module supports up to eight timers, with a maximum resolution of 8-bits. The timers can be used for a variety of tasks, such as generating pulse width modulated signals, timing events, and counting.

The timer module also features interrupt support, allowing for an interrupt to be generated when a timer reaches a specific value. This makes the general-purpose timer module an ideal solution for time-sensitive embedded systems.

Conclusion

The MCF51QM128VHS is a highly-integrated family of mixed-signal microcontrollers based on a ColdFire® V1 core. It features a wide array of integrated peripherals, such as a USB 2.0 Full-Speed On-The-Go port, a CAN interface, and an LCD controller, all of which are housed in a low-profile ball grid array package. This makes the MCF51QM128VHS an ideal solution for embedded applications with limited board space, such as industrial and consumer products and medical, automotive, and other applications.
