Introduction

NXP Semiconductors

1.6.20.3

Analog-To-Digital Converter (ADC)

•

Four independent ADCs with 12-bit A/D resolution

•

Common mode conversion range of 0–5 V or 0–3.3 V

•

Twenty-two single-ended input channels

•

Supports eight FIFO queues with fixed priority

•

Queue modes with priority-based preemption; initiated by software command, internal, or external triggers

•

DMA and interrupt request support

1.6.20.4

eTimer module

Three 16-bit general purpose up/down timer/counters per module are implemented with the following features:

•

Ability to operate up to platform frequency

•

Individual channel capability

— Input capture trigger

— Output compare

— Double buffer (to capture rising edge and falling edge)

— Separate prescaler for each counter

— Selectable clock source

— 0–100% pulse measurement

— Rotation direction flag (quad decoder mode)

•

Maximum count rate

— Equals peripheral clock/2 for external event counting

— Equals peripheral clock for internal clock counting

•

Cascadeable counters

•

Programmable count modulo

•

Quadrature decode capabilities

•

Counters can share available input pins

•

Count once or repeatedly

•

Preloadable counters

•

Pins available as GPIO when timer functionality is not in use

•

DMA support

1.6.21

Redundancy Control and Checker Unit (RCCU)

The RCCU checks all outputs of the sphere of replication (addresses, data, control signals). It has the following features:

•

Duplicated module to enable high diagnostic coverage (check of checker)

•

Replicated IP to be used as checkers on the PBRIDGE output, Flash Controller output, SRAM output, DMA Channel

Mux inputs

1.6.22

Software Watchdog Timer (SWT)

This module implements the features below:

•

Replicated periphery to provide safety measures respective to high safety integrity levels (for example, SIL 3, ASIL D)

•

Fault-tolerant output

•

Safe internal RC oscillator as reference clock

•

Windowed watchdog
