The H8SX/1665 Group enhances the analog functions (ADC and DAC) of theexisting H8SX/1668R Group. Peripheral functions have been further enhanced witha 10-bit ADC (2units) which achieves a conversion speed of 1 μs (2.7 times theconventional speed) and an on-chip 10-bit DAC (8-bit for H8SX/1668R). The H8SX/1665 Group is also pin-to-pin compatible with the H8SX/1668R Group.

Hardware Design Support

Title Description
IBIS/BSDL IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board. BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
