OM12001 (ATOP) NXP Semiconductors Telematics 6.1.3 Ethernet Ethernet block supports bus clock rates of up to 100 MHz. The Ethernet block contains a full featured 10 Mbit/s or 100 Mbit/s Ethernet MAC designed to provide optimized performance through the use of DMA hardware acceleration. Features include a generous suite of control registers, half or full duplex operation, flow control, control frames, hardware acceleration for transmit retry, receive packet filtering and wake-up on LAN activity.
OM12001 (ATOP) NXP Semiconductors Telematics • Global Acceptance Filter recognizes 11-bit and 29-bit receive identifiers for all CAN buses • Acceptance Filter can provide FullCAN-style automatic reception for selected Standard Identifiers • Full CAN messages can generate interrupts 6.1.6 Power saving modes 6.1.6.
OM12001 (ATOP) NXP Semiconductors Telematics 6.1.6.2 Power modes The LPC1768 support a variety of power control features. There are four special modes of processor power reduction: • • • • Sleep Deep-sleep Power-down Deep power-down The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements.
OM12001 (ATOP) NXP Semiconductors Telematics Power-down mode: Power-down mode does everything that Deep-sleep mode does, but also turns off the power to the IRC oscillator and the flash memory. This saves more power but requires waiting for resumption of flash operation before execution of code or data access in the flash memory can be accomplished. Deep power-down mode: The Deep power-down mode can only be entered from the RTC block.
OM12001 (ATOP) NXP Semiconductors Telematics • precharge mode: Precharge mode is completely under HW control and will continue until the battery voltage is high enough so that baseband can boot. During precharge, ATOP will provide a 200 mA current. As SW is not yet booted, temperature will not be controlled, i.e. precharge will occur even if battery is outside of advised range for a battery • fast charge: If battery level is higher than 3.1V (i.e.

Charging circuitry Additionally other pins should be connected as follows: • VBAT_SENSE_P must be connected to the battery • VBAT_SENSE_N must be connected to ground • BB_BAT_THERM must be connected to a 10 kOhm pull-down, or to the battery thermistor 7.
OM12001 (ATOP) NXP Semiconductors Telematics 7.3 Current source OM12001 (ATOP) handles internally all its voltage conversion. For Utility Processor, a separate input, VBAT_MC_SNK, is used. Internally, a LDO, controlled by VDD_3V0_SRC_ENA (active high, with internal pull-up), will convert it to the 3V required by the Utility Processor. As described in Figure 7, the output of the LDO is also available externally to power external component, up to a maximum of 100 mA can be drawn.
