FUJITSU MICROELECTRONICS DATA SHEET DS07-13751-2E 16-bit Microcontroller CMOS F2MC-16LX MB90820B Series MB90822B/823B/F822B/F823B/F828B/V820B ■ DESCRIPTION The MB90820B series is a line of general-purpose, Fujitsu 16-bit microcontrollers designed for process control applications which require high-speed real-time processing, such as consumer products. While inheriting the AT architecture of the F2MC family, the instruction set for the F2MC-16LX CPU core of the MB90820B series incorporates additional instructions for high-level languages, supports extended addressing modes, and contains enhanced multiplication and division instructions as well as a substantial collection of improved bit manipulation instructions. In addition, the MB90820B series has an on-chip 32-bit accumulator which enables processing of long-word data. The peripheral resources integrated in the MB90820B series include : an 8/10-bit A/D converter, 8-bit D/A converters, UARTs (SCI) 0, 1, multi-functional timer (16-bit free-run timer, input capture units (ICUs) 0 to 3, output compare units (OCUs) 0 to 5, 16-bit PPG timer 0, waveform generator), 16-bit PPG timer 1, 2, PWC 0, 1, 16-bit reload timer 0, 1 and DTP/external interrupt. Note : F2MC is the abbreviation of FUJITSU Flexible Microcontroller. ■ FEATURES • Minimum execution time of instruction : 42 ns / 4 MHz oscillation (uses PLL clock multiplication) maximum multiplier = 6 • Maximum memory space 16 M bytes, Linear/bank access • Instruction set optimized for controller applications Supported data types : bit, byte, word, and long-word types Standard addressing modes : 23 types 32-bit accumulator enhancing high-precision operations Signed multiplication/division instructions and enhanced RETI instructions (Continued) For the information for microcontroller supports, see the following web site. http://edevice.fujitsu.com/micom/en-support/ Copyright©2008-2009 FUJITSU MICROELECTRONICS LIMITED All rights reserved 2009.1 Free Datasheet http://www.datasheet4u.com/ MB90820B Series (Continued) • Enhanced high level language (C) and multi-tasking support instructions Use of a system stack pointer Symmetrical instruction set and barrel shift instructions • Program patch function (for two address pointers) • Increased execution speed : 4-byte instruction queue • Powerful interrupt function Up to eight priority levels programmable External interrupt inputs : 8 channels • Automatic data transmission function independent of CPU operation Up to 16 channels for the extended intelligent I/O service DTP request inputs : 8 channels • Internal ROM Flash memory : 64 K/128 K bytes with flash security MASK ROM : 64 K/128 K bytes • Internal RAM Evaluation product : 16 K bytes Flash memory : 4 K/8 K bytes MASK ROM : 4 K bytes • General-purpose ports Up to 66 channels (ports where pull-up resistor can be configured : 32 channels) • A/D Converter (RC) : 16 channels 8/10-bit resolution selectable Conversion time : Min 3 µs (24 MHz operation, including sampling time) • 8-bit D/A Converter : 2 channels • UART : 2 channels • 16-bit PPG timer : 3 channels Mode switching function provided (PWM mode or one-shot mode) ch.0 can be worked with multi-functional timer or independently • 16-bit reload timer : 2 channels • 16-bit PWC timer : 2 channels • Clock supervisor • Multi-functional timer Input capture : 4 channels Output compare with selectable buffer : 6 channels Free-run timer with up or up-down mode selection and selectable buffer: 1 channel 16-bit PPG timer : 1 channel Waveform generator : (16-bit timer : 3 channels, 3-phase waveform or dead time) • Time-base timer/watchdog timer : 18-bit • Low-power consumption mode : Sleep mode Stop mode CPU intermittent operation mode • Package : LQFP-80 (FPT-80P-M21 : 0.50 mm pitch) LQFP-80 (FPT-80P-M22 : 0.65 mm pitch) QFP-80 (FPT-80P-M06 : 0.80 mm pitch) • CMOS technology 2 DS07-13751-2E Free Datasheet http://www.datashee MB90820B Series ■ PRODUCT LINEUP Part number Item Classification ROM size RAM size MB90V820B Evaluation product — 16 K bytes MB90F822B MB90F823B MB90F828B MB90822B MB90823B Flash memory product with flash security 64 K bytes 128 K bytes 128 K bytes 8 K bytes 4 K bytes MASK ROM product 64 K bytes 128 K bytes 4 K bytes CPU function Number of instruction : 351 Minimum execution time : 42 ns / 4 MHz (PLL × 6) Addressing mode : 23 Data bit length : 1, 8, 16 bits Maximum memory space: 16 M bytes I/O port (CMOS) : 66 Pulse width counter timer : 2 channels Timer function (select the counter timer from three internal clocks) Various pulse width measuring function (“H” pulse width, “L” pulse width, rising edge to falling edge period, falling edge to rising edge period, rising edge to rising edge period and falling edge to falling edge period) UART : 2 channels With full-duplex double buffer (8-bit length) Clock asynchronized or clock synchronized transmission (with start and stop bits) can be selected and used.
