The MC9S08SH32VTL is a 8-bit microcontroller from Freescale Semiconductor from its HCS08 family. This Microcontroller has an internal CPU core integrated with an 8KB Flash Program Memory and an ADC (Analog to Digital Converter)

Application Field

This controller provides a completely integrated solution for embedded designs and is used in many areas of industrial and commercial applications. It is used in automatic water controllers, industrial automation systems, medical equipment, battery powered instruments, pedestrian counters, antivibration systems, lift control systems and switches.

The MC9S08SH32VTL is designed to provide increased power-saving performance, allowing designs to remain operational for longer periods without the need to replace costly batteries. It also provides more program memory and additional I/O ports compared to other devices in the HCS08 family, allowing more functions and operations to take place on a single chip.

Working Principle

The MC9S08SH32VTL is an 8-bit Microcontroller and uses a Reduced Instruction Set Computer (RISC) architecture, which allows for simpler instructions that can be executed in fewer clock cycles. The CPU core consists of a two-stage pipeline, meaning that instructions can be fetched, decoded, and executed in overlapping groups of two instructions.

The MC9S08SH32VTL supports up to an 8-channel 10-bit Analog-to-Digital Converter (ADC) module and is capable of sampling up to 24-bit conversion results. The ADC module also features an internal regulated reference voltage that can be used for higher accuracy measurements. The onboard Program Flash Memory can hold up to 8KB of program code, allowing more complex applications to fit into a single device.

The controller also comes with an Enhanced Direct Memory Access (EDMA) module that allows data transfers to take place without the processor having to be involved. The EDMA module can be set up to transfer data directly to and from other devices without the need for any processor intervention, allowing more efficient use of the CPU cycles.

The MC9S08SH32VTL is powered by a low voltage supply and comes with multiple low-power modes that can reduce power consumption when the device is not actively being used. This makes it an ideal choice for battery-powered applications, where long battery life is essential.

Conclusion

The MC9S08SH32VTL is a 8-bit microcontroller from Freescale Semiconductor from its HCS08 family and is widely used in embedded applications, where long battery life is essential and more complex applications need to fit into a single chip. It comes with an internal CPU core and an 8KB Flash Program Memory as well as an ADC, allowing more accurate measurements to be taken. It also supports up to an 8-Channel 10-bit ADC, an EDMA module, and provides multiple low-power modes when not actively being used.
