Nowadays embedded system plays an increasingly important role in our life. Embedded technology is divided into Application-Specific Integrated Circuits (ASICs), Microcontroller, Digital signal Processor (DSP), Programmable Logic Device (PLD), and so on. Microcontroller is an electronic device with a high level of integration, used to complete the specified control strategy. S9S12GN16BMLC is a low-power 8-bit microcontroller developed by Freescale. It is widely used in some embedded control applications, such as automotive, appliance, Consumer Electronics, industrial control and so on.

The architecture of S9S12GN16BMLC is based on HCS12X series. It is designed for low-cost embedded applications. The operating frequency range is 1MHz~20MHz and the minimum instruction execution time is 1/20M per instruction.

S9S12GN16BMLC is encased in a QFP44 package. It has a total of 128K words of on-chip flash memory. This memory can be protected using the ECD circuit. It will lock the contents of the protected page once it is programmed. It also has 4K words of on-chip RAM which can be used as protected data memory.

The S9S12GN16BMLC has two advanced core features; the Fast Interrupt Response (FIRST) and the MAC (Multiple-Access Controller). The FIRST feature accelerates response time when the interrupt is tripped by responding quickly to the interrupt. The MAC feature allows I/Os from different applications to share the same physical port, simplifying system design and reducing system cost.

The S9S12GN16BMLC also integrates 32 I/O pins, 2 Timer Input Capture modules, 2 Timers modules, 2 SCI serial interfaces, 1 Capture Timer Module, 2 Interrupts sources, 1 SPI interface, and 2 PWM modules. All features make this microcontroller an ideal solution for automotive and industrial control.

As a low power microcontroller, S9S12GN16BMLC is also energy efficient. It has an operating voltage of 1.8V to 4.3V, and can effectively reduce power consumption.

To sum up, S9S12GN16BMLC is a low-cost and low-power microcontroller optimized for embedded control applications. It has excellent features such as 128K flash memory, 4K RAM, 32 I/O pins, multiple advanced core features and excellent energy efficiency. It is suitable for automotive, appliance, consumer electronics, and industrial control applications.
