FAQ
What is the maximum operating frequency and required supply voltage for SAF-C164CI-L25M CA?
The SAF-C164CI-L25M CA operates at up to 25 MHz with a nominal 5 V ±10% supply. Its internal PLL accepts input frequencies from 1 MHz to 20 MHz and multiplies them by factors of 1.5× to 5× to achieve the 25 MHz system clock. The device is not rated for 3.3 V operation and requires stable 5 V regulation with adequate decoupling near VDD pins.
Does SAF-C164CI-L25M CA include on-chip program memory?
No, the SAF-C164CI-L25M CA is a ROM-less derivative. It relies on external program memory accessed via its 4 MB external bus interface. This enables field firmware updates and eliminates mask ROM NRE costs. Boot code execution begins from external memory after reset, controlled by the EA (External Access) pin state.
How many CAN message objects does the on-chip CAN controller support?
The SAF-C164CI-L25M CA supports 15 message objects in its on-chip CAN controller, compliant with ISO 11898-1 Rev. 2.0B. These objects can be configured as transmit or receive buffers with individual ID masking and acceptance filtering, enabling efficient handling of multiple CAN identifiers without CPU polling.
What debug and development tools are supported for this microcontroller?
Infineon provides C-compilers, macro-assemblers, HLL debuggers, simulators, and logic analyzer disassemblers for the C164CI. Hardware tools include ICE-based emulators and evaluation boards with JTAG or OCDS interfaces. The on-chip bootstrap loader also allows firmware updates via UART without external programming hardware.
