    PIC18F67J50 which has 128K of programming space and has most of the features that you mentioned above
    I am to lazy to look it up...
    Does the PIC18F67J50 have the features Walter has in red?

    The 18F67J50 doesn't have the RTCC and the 12-bit ADC. Also, I don't think it has the crystal-less USB feature of the chips Scalerobotics has mentioned. Below are the highlights of the 18F67J50 taken from the datasheet.

    Universal Serial Bus Features:
    • USB V2.0 Compliant SIE
    • Low Speed (1.5 Mb/s) and Full Speed (12 Mb/s)
    • Supports Control, Interrupt, Isochronous and
    Bulk Transfers
    • Supports up to 32 Endpoints (16 bidirectional)
    • 3.9-Kbyte Dual Access RAM for USB
    • On-Chip USB Transceiver
    Flexible Oscillator Structure:
    • High-Precision PLL for USB
    • Two External Clock modes, up to 48 MHz
    • Internal 31 kHz Oscillator, Tunable Internal
    Oscillator, 31 kHz to 8 MHz
    • Secondary Oscillator using Timer1 @ 32 kHz
    • Fail-Safe Clock Monitor:
    - Allows for safe shutdown if any clock stops
    Peripheral Highlights:
    • High-Current Sink/Source 25 mA/25mA
    (PORTB and PORTC)
    • Four Programmable External Interrupts
    • Four Input Change Interrupts
    • Two Capture/Compare/PWM (CCP) modules
    • Three Enhanced Capture/Compare/PWM (ECCP)
    modules:
    - One, two or four PWM outputs
    - Selectable polarity
    - Programmable dead time
    - Auto-shutdown and auto-restart
    • Two Master Synchronous Serial Port (MSSP)
    modules supporting 3-Wire SPI (all 4 modes) and
    I2C™ Master and Slave modes
    • 8-Bit Parallel Master Port/Enhanced Parallel
    Slave Port with 16 Address Lines
    • Dual Analog Comparators with Input Multiplexing
    Peripheral Highlights (continued):
    • 10-Bit, up to 12-Channel Analog-to-Digital (A/D)
    Converter module:
    - Auto-acquisition capability
    - Conversion available during Sleep
    • Two Enhanced USART modules:
    - Supports RS-485, RS-232 and LIN 1.2
    - Auto-wake-up on Start bit
    - Auto-Baud Detect
    External Memory Bus
    (80-pin devices only):
    • Address Capability of up to 2 Mbytes
    • 8-Bit or 16-Bit Interface
    • 12-Bit, 16-Bit and 20-Bit Addressing modes
    Special Microcontroller Features:
    • 5.5V Tolerant Inputs (digital-only pins)
    • Low-Power, High-Speed CMOS Flash Technology
    • C Compiler Optimized Architecture for
    Re-Entrant Code
    • Power Management Features:
    - Run: CPU on, peripherals on
    - Idle: CPU off, peripherals on
    - Sleep: CPU off, peripherals off
    • Priority Levels for Interrupts
    • Self-Programmable under Software Control
    • 8 x 8 Single-Cycle Hardware Multiplier
    • Extended Watchdog Timer (WDT):
    - Programmable period from 4 ms to 131s
    • Single-Supply In-Circuit Serial Programming™
    (ICSP™) via Two Pins
    • In-Circuit Debug (ICD) with 3 Breakpoints via
    Two Pins
    • Operating Voltage Range of 2.0V to 3.6V
    • On-Chip 2.5V Regulator
    • Flash Program Memory of 10000 Erase/Write
    Cycles and 20-Year Data Retention
