Description
The ST7LITE49M is a member of the ST7 microcontroller family. All ST7 devices are based
on a common industry-standard 8-bit core, featuring an enhanced instruction set.
The ST7LITE49M features Flash memory with byte-by-byte in-circuit programming (ICP)
and in-application programming (IAP) capability.
Under software control, the ST7LITE49M device can be placed in Wait, Slow, or Halt mode,
reducing power consumption when the application is in idle or standby state.
The enhanced instruction set and addressing modes of the ST7 offer both power and
flexibility to software developers, enabling the design of highly efficient and compact
application code. In addition to standard 8-bit data management, all ST7 microcontrollers
feature true bit manipulation, 8x8 unsigned multiplication and indirect addressing modes.
The ST7LITE49M features an on-chip Debug Module (DM) to support in-circuit debugging
(ICD). For a description of the DM registers, refer to the ST7 ICC protocol reference manual.
