• Manufacturer Part Number: SAF-XC164GM-8F20F
• Description: 16-Bit Single-Chip Microcontroller with C166SV2 Core
• Manufacturer: INFINEON [Infineon Technologies AG]

can consist of up to 16 word wide (R0 to R15) and/or byte wide (RL0, RH0, …, RL7, RH7)
so-called General Purpose Registers (GPRs).
The upper 256 bytes of the DPRAM are directly bit addressable. When used by a GPR,
any location in the DPRAM is bit addressable.
1024 bytes (2
Register areas (SFR space and ESFR space). SFRs are word wide registers which are
used for controlling and monitoring functions of the different on-chip units. Unused SFR
addresses are reserved for future members of the XC166 Family. Therefore, they should
either not be accessed, or written with zeros, to ensure upward compatibility.
