5 Operating Frequency and Power Management

The F2837xD/S devices have a maximum operating frequency of 200 MHz (120 MHz for 2807x). By comparison, the F2833x/23x devices have a maximum operating frequency of 150 MHz or 100 MHz depending upon the specific device family member.

The F2833x/23x devices require 3.3 V and 1.8 V for operation whereas the F2837xD/S/07x devices require 3.3 V and 1.2 V. In the 2807x device alone, the 1.2 V can be generated with the on-chip voltage regulator (VREG). The F2837xD/S/07x devices have a built-in power-on reset (POR) circuit. During power up, the POR circuit drives the XRS pin low. A watchdog or NMI watchdog reset also drives the pin low. An external circuit may drive the pin to assert a device reset. The POR circuit keeps the I/Os in a high-impedance state during power up. For details related to power management, see the device-specific data sheet.
