Features
• One high resolution eFlexPWM module with up to 12
PWM outputs, including 8 channels with 312ps
resolution NanoEdge placement
• This family of digital signal controllers (DSCs) is
based on the 32-bit 56800EX core. On a single chip,
each device combines the processing power of a DSP
and the functionality of an MCU, with a flexible set of
peripherals to support many target applications:
– Industrial control
• Communication interfaces
– Up to two high-speed queued SCI (QSCI) modules
with LIN slave functionality
– One queued SPI (QSPI) modules
– Motion control
– Up to two LPI2C modules (Support Full PMBus)
– Home appliances
– General-purpose inverters
• Timers
– One 16-bit quad timer (1 x 4 16-bit timer)
– Two 32-bit Periodic Interval Timers (PITs)
– One Quadrature Decoder (QDC)
– Smart sensors, fire and security systems
– Wireless charging
– Switched-mode power supply and power
management
• Security and integrity
– Uninterruptible power supplies (UPS)
– Solar inverter
– Medical monitoring applications
– Cyclic Redundancy Check (CRC) generator
– Windowed Computer operating properly (COP)
watchdog
– External Watchdog Monitor (EWM)
• DSC based on 32-bit 56800EX core
– Up to 100 MIPS at 100 MHz core frequency in fast
mode
• Clocks
– On-chip oscillators: 200 kHz, and 8/2MHz IRC
– Crystal / resonator oscillator
– DSP and MCU functionality in a unified, C-efficient
architecture
• System
• On-chip memory
– 4-channel enhanced DMA controller, supporting up
to 63 request sources
– Up to 128 KB flash memory
– Up to 20 KB data/program RAM
– Both on-chip flash memory and RAM can be
mapped into both program and data memory spaces
– Boot ROM (supports boot from SCI, I2C)
– Integrated power-on reset (POR) and low-voltage
interrupt (LVI) and brown-out reset module
– Inter-Module Crossbar and Event Generator
– JTAG/enhanced on-chip emulation (EOnCE) for
unobtrusive, real-time debugging
• Analog
– Two high-speed, 12-bit ADCs with dynamic x1, x2,
and x4 programmable amplifier
– Two operational amplifiers, programmable gain up
to x16
• Operating characteristics
– Single supply: 2.7 V to 3.6 V
– Operation ambient temperature (V): -40 to 105°C
– Operation ambient temperature (M): -40 to 125°C
– Up to four analog comparators with integrated 8-bit
DAC references
– One 12-bit digital-to-analog converters (DAC)
– On-chip temperature sensors
• 64-pin LQFP, 48-pin LQFP, 32-pin LQFP and QFN
packages
