MC9S08QE4CTG Description
The MC9S08QE4CTG is an 8-bit Flexis QE MCUs. Our first family in the Flexis series is the S08QE family, which consists of a pair of pin-compatible 8-bit and 32-bit devices. The link point of the NXP? Controller Continuum, where 8- and 32-bit compatibility becomes a reality, is the Flexis line of controllers.
The S08QE128 pushes the limits of the performance of the 8-bit architecture with 128 KB of flash, 24 analog-to-digital converters (ADC) channels, and a bus frequency of up to 25 MHz. The 8-bit S08QE128 device and the 32-bit MCF51QE128 are interchangeable in terms of pins, peripherals, and tools. With their shared peripherals and development tools, they offer the greatest degree of migration flexibility.
MC9S08QE4CTG Features
– ADC — 10-channel, 12-bit resolution; 2.5μs conversion time; automatic compare function; 1.7 mV/°C temperature sensor; internal bandgap reference channel; operation in stop3; fully functional from 3.6 V to 1.8 V
– ACMPx — Two analog comparators with selectable interrupt on rising, falling, or either edge of comparator output; compare option to fixed internal bandgap reference voltage; outputs can be optionally routed to TPM module; operation in stop3
– SCI — Full-duplex non-return to zero (NRZ); LIN master extended break generation; LIN slave extended break detection; wake-up on active edge
– SPI — Full-duplex or single-wire bidirectional; double-buffered transmit and receive; master or slave mode; MSB-first or LSB-first shifting
– IIC — Up to 100 kbps with maximum bus loading; multi-master operation; programmable slave address; interrupt driven byte-by-byte data transfer; supporting broadcast mode and 10-bit addressing
– TPMx — Two 3-channel (TPM1 and TPM2); selectable input capture, output compare, or buffered edge- or center-aligned PWM on each channel
– RTC — (Real-time counter) 8-bit modulus counter with binary or decimal based prescaler; external clock source for precise time base, time-of-day, calendar or task scheduling functions; free running on-chip low power oscillator (1 kHz) for cyclic wakeup without external components; runs in all MCU modes
– 26 GPIOs, one output-only pin and one input-only pin
– Eight KBI interrupts with selectable polarity
– Hysteresis and configurable pullup device on all input pins; configurable slew rate and drive strength on all output pins.
– 32-pin LQFP, 32-pin QFN, 28-pin SOIC, 20-pin SOIC, 16-pin PDIP, 16-pin TSSOP
– Up to 20 MHz CPU at 3.6 V to 1.8 V across temperature range of –40 °C to 85 °C
– HC08 instruction set with added BGND instruction
– Support for up to 32 interrupt/reset sources
– Flash read/program/erase over full operating voltage and temperature
– Random-access memory (RAM)
– Security circuitry to prevent unauthorized access to RAM and flash contents
– Two low power stop modes
– Reduced power wait mode
– Low power run and wait modes allow peripherals to run while voltage regulator is in standby
– Peripheral clock gating register can disable clocks to unused modules, thereby reducing currents
– Very low power external oscillator that can be used in stop2 or stop3 modes to provide accurate clock source to real time counter
– 6 μs typical wake-up time from stop3 mode
– Oscillator (XOSC) — Loop-control Pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz
– Internal Clock Source (ICS) — Internal clock source module containing a frequency-locked-loop (FLL) controlled by internal or external reference; precision trimming of internal reference allows 0.2% resolution and 2% deviation over temperature and voltage; supporting bus frequencies from 1 MHz to 10 MHz
– Watchdog computer operating properly (COP) reset with option to run from dedicated 1 kHz internal clock source or bus clock
– Low-voltage warning with interrupt
– Low-voltage detection with reset or interrupt
– Illegal opcode detection with reset
– Illegal address detection with reset
– Flash block protection
– Single-wire background debug interface
– Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module)
– On-chip in-circuit emulator (ICE) debug module containing two comparators and nine trigger modes; eight deep FIFO for storing change-of-flow addresses and event-only data; debug module supports both tag and force breakpoints
