Features overview

On-chip modules within SPC572Lx include the following features:

•

1 main CPU, single issue, 32-bit CPU core complex (e200z2)

–

Power Architecture embedded specification compliance

–

Instruction set enhancement allowing variable length encoding (VLE), encoding a

mix of 16-bit and 32-bit instructions, for code size footprint reduction

–

Single-precision floating point operations

–

Saturation Instructions Extension adding scalar saturating arithmetic support to

the PowerISA Integer Saturation (ISAT)

•

1568 KB (1536 KB code flash + 32 KB data flash) on-chip flash memory

–

Supporting multiple blocks allowing EEPROM emulation

–

RWW between data EEPROM and code flash memory

•

64 KB general-purpose data SRAM

•

System Memory Protection Unit (SMPU)

•

16-channel Direct Memory Access controllers (eDMA) with two channel multiplexers for

up to 60 DMA sources

•

Interrupt Controller (INTC) supporting up to 1024 interrupt sources (all are not

assigned)

•

System Timer Module (STM)

•

2 Software Watchdog Timers (SWT)

•

2 Periodic Interrupt Timers (PIT)

–

1 PIT with four standard 32-bit timer channels

–

1 PIT with two 32-bit timer channels which can be combined into one 64-bit

channel

•

Single phase-locked loop with stable clock domain for peripherals and core (PLL)

•

Single crossbar switch architecture for concurrent access to peripherals, flash memory,

or SRAM from multiple bus masters

•

System Integration Unit Lite (SIUL2)

•

Boot Assist Flash (BAF) supports factory programming using a serial bootload through

the UART Serial Boot Mode Protocol (physical interface (PHY) can be e.g., UART and

CAN)

•

PASS module (supporting 256-bit JTAG password protection)

•

Device life cycle monitoring

•

Generic Timer Module (GTM101)

•

Enhanced analog-to-digital converter system with:

–

Three 12-bit SAR analog converters

–

One 16-bit Sigma-Delta analog converter

•

Decimation unit to support SD ADC data conditioning

•

1 Deserial Serial Peripheral Interface (DSPI) module

•

2 LIN and UART communication interfaces (LINFlexD) modules

•

1 microsecond-bus channel (composed of one DSPI and one LINFlexD)

•

4 SENT (Single Edge Nibble Transmission) channels

•

2 Modular Controller Area Network (M_CAN) modules
