S9S08SL8F1MTL

S9S08SL8F1MTL is a low-power, high-performance 8-bit microcontroller (MCU) for embedded control applications, optimized for low system cost.

Application Field

S9S08SL8F1MTL is designed to meet the cost, code size and performance requirements of a wide range of real-time embedded control applications. It is used for a variety of industrial, consumer, medical, automotive and other applications. Specifically, it is an efficient and economical solution for the mass storage motor, motor drive, home appliance, security system, smart meter and electric meter management, meter reader, electric water heater, lighting, entertainment equipment and other appliance control.

Working Principle

The S9S08SL8F1MTL Flash microcontroller implements a single-cycle, modified Harvard bus architecture, which includes an internal 8-bit data bus and 16-bit instruction bus. The core CPU is based on the S09 CISC (Complex Instruction Set Computer) family of RISC (Reduced Instruction Set Computing) instruction set microhelpers, and is clocked by a 32.768 millisecond cycle machine clock of up to 20 MHz. . Furthermore, the microcontroller supports certain language operations, storage space, interrupt control and I/O port control. To make use of these features, the microcontroller requires a system clock as well as power supply for its integral circuits.

The S9S08SL8F1MTL has a non-multiplexed 8-bit bi-directional port, which can be used as either an input port or an output port. It also has three 16-bit timer/counter channels, providing four different timers/counters. Its I/O port control enables functions such as strong pull/pull-up, weak pull/pull-up, TMR/CNT input and output, and analog port input.

In addition, the S9S08SL8F1MTL\'s on-chip power management unit (PMU) is an independently operated 32-bit motion processor that controls the power saving behaviors of the microcontroller while it is idle or in a low power state. It provides autonomous power management by automatically switching the power of selected peripheral modules on and off.

The S9S08SL8F1MTL offers 7-channel cyclic redundancy check (CRC) capability for user data transfers and over-the-air communication. It also features Direct Memory Access (DMA) technology, which enables fast, efficient data transfer from memory to peripheral devices.

Rounding out the platform are two 8-bit ADC (Analog-to-Digital Converter) channels, an on-chip 10-bit watchdog timer, an internally generated reset and wake-up source with programmable interval, and a non-maskable interrupt (NMI).

Conclusion

The S9S08SL8F1MTL is a powerful, cost-effective and efficient MCU solution for embedded control applications. With its on-chip power management unit, cyclic redundancy check capability, Direct Memory Access technology, and other features, it provides the ideal platform for a wide range of industrial and consumer applications. Additionally, its small form factor and low power consumption enable the rapid development of efficient and cost-effective solutions.
