STM8L family compatibility

1.1

Family concept

The STM8L family is one of a growing number of different STM8 microcontroller families.

All these STM8 microcontroller families are based on a common robust and low-cost 8-bit

high performance core with a rich set of enhanced peripherals. This ensures a high level of

compatibility within the STM8L ‘world’, especially in terms of software development,

compilers, debugging environment, programming tools and driver libraries.

The STM8L product family offers a wide choice of memory sizes and package types to fit

different application requirements as closely as possible. Consequently, when there are new

requirements on the application side, it can make sense to switch to another STM8L type

with different memory capacity or package size.

The STM8L family includes a product line divided into two main sub-families:

●

STM8L15x/STM8L16x sub-family of microcontrollers with different memory densities,

packages and peripherals.

–

The low density STM8L15x devices are the STM8L151C2/K2/G2/F2,

STM8L151C3/K3/G3/F3 microcontrollers with a 4-Kbyte or 8-Kbyte Flash memory

density.

–

The medium density STM8L15x devices are the STM8L151C4/K4/G4,

STM8L151C6/K6/G6, STM8L152C4/K4/G4 and STM8L152C6/K6/G6

microcontrollers with a 16-Kbyte or 32-Kbyte Flash memory density.

–

The medium+ density STM8L15x devices are the STM8L151R6 and

STM8L152R6 microcontrollers with a 32-Kbyte Flash memory density. They offer

a wider range of peripherals than the medium density devices.

–

The high density STM8L15x devices are the STM8L151x8 and STM8L152x8

microcontrollers with a Flash memory density equal to 64 Kbytes. They offer the

same peripheral set as medium+ density devices.

–

The high density STM8L162x devices are the STM8L162x8 microcontrollers

where the Flash memory density is equal to 64 Kbytes. They offer the same

peripheral set as high density STM8L152 devices plus the AES hardware

accelerator.

●

STM8L10x low density sub-family where the Flash memory density ranges between 4

and 8 Kbytes. The STM8L10x MCUs are ideal for cost-sensitive applications with low

code density.

Both sub-families provide a complete set of essential peripherals. STM8L10x devices target

applications requiring reduced cost, lower memory capacity, fewer GPIOs and less

advanced features.

The wide range of available pin-counts and package sizes is discussed in Chapter 3.1:

Package pinout.
