HD404829R Series AS Microcomputer Incorporating a LCD controller/Driver Circuit ADE-202-057C Rev.4 Sept. 1999 Description The HD404829R series incorporates an 8-bit A/D converter (four channels), a Liquid Crystal Display (LCD) and a serial interface, and has large-current Input/Output (I/O) pins. The series is a 4-bit single-chip microcomputer best used in the AV equipment such as CD radio cassette tape recorders which require the LCD display control. The HD404829R Series, with a 32.768kHz sub-oscillator for clocks, counts up the system clock and a variety of power modes can reduce power consumption. The HD4074829 is a ZTAT TM microcomputer which incorporates a PROM. System development period has been dramatically reduced so that the process from debugging to mass production is smooth. (The PROM programming specifications are the same as those for Type 27256.) ZTAT TM: Zero Turn Around Time ZTAT is a trademark of Hitachi Ltd. Features • 1,876-digit × 4-bit RAM • 44 I/O pins, including 10 high-current pins (15 mA, max.) and 20 pins multiplexed with LCD segment pins • Four timer/counters • 8-bit input capture circuit • Three timer outputs (including two PWM out-puts) • Two event counter inputs (including one double-edge function) • Clock-synchronous 8-bit serial interface • A/D converter (4 channels × 8 bits) • LCD controller/driver (52 segments × 4 commons) • Built-in oscillators  Main clock: 4.2-MHz ceramic (an external clock is also possible)  Subclock: 32.768-kHz crystal • Eleven interrupt sources  Five by external sources, including three double-edge functions HD404829R Series  Six by internal sources • Subroutine stack up to 16 levels, including interrupts • Four low-power dissipation modes  Subactive mode  Standby mode  Watch mode  Stop mode • One external input for transition from stop mode to active mode • Instruction cycle time (min.): 0.95 µs (fOSC = 4.2 MHz) • Operation voltage VCC = 2.7 V to 6.0 V (HD404829R) VCC = 2.7 V to 5.5 V (HD4074829) • Two operating modes  MCU mode  MCU/PROM mode (HD4074829 only) 2 HD404829R Series Ordering Information Type Mask ROM Product Name HD404828R Model Name HD404828RH HD404828RFS HD404828RTF HD4048212R HD4048212RH HD4048212RFS HD4048212RTF HD404829R HD404829RH HD404829RFS HD404829RTF ZTAT TM ROM (Words) 8,192 Package 100-pin plastic QFP (FP-100B) 100-pin plastic QFP (FP-100A) 100-pin plastic TQFP (TFP-100B) 12,288 100-pin plastic QFP (FP-100B) 100-pin plastic QFP (FP-100A) 100-pin plastic TQFP (TFP-100B) 16,384 100-pin plastic QFP (FP-100B) 100-pin plastic QFP (FP-100A) 100-pin plastic TQFP (TFP-100B) HD4074829 HD4074829H HD4074829FS HD4074829TF 16,384 100-pin plastic QFP (FP-100B) 100-pin plastic QFP (FP-100A) 100-pin plastic TQFP (TFP-100B) Caution about operation! It has been confirmed that the HD404829R Series, same as the ZTAT TM version HD4074829 and the conventional HD404829 Series, satisfies the electrical properties given on the data sheets, etc. However, effective values of the electrical properties, the operating margin, and the noise margin may differ with the manufacturing processes, on-chip ROM, and layout patterns. Therefore, conduct an evaluation test of your system using the ZTATTM version and the mask ROM version. Also conduct a similar evaluation test for checkup before replacing your conventional product with the HD404829R Series. 3 HD404829R Series List of Functions Product name ROM (Words) RAM (Digits) I/O Large-current I/O pins LCD segment multiplexed pins Timer / Counter Input capture Timer output Event input Serial interface A/D converter LCD controller / driver circuit Interrupts External Internal Low-Power Dissipation Mode Stop mode Watch mode Standby mode Subactive mode Main Oscillator Ceramic oscillation Crystal oscillation Sub oscillator Crystal oscillation HD404828R 8,192 HD4048212R 12,288 1,876 44 (max) 10 (Sink 15 mA max) 20 4 8 bit × 1 3 (PWM output possible for 2) 2 (edge selection possible for 1) 1 (8-bit syncronous) 8 bit × 4 channels Max. 52 seg × 4 com 5 (edge selection possible for 3) 6 4 O O O O O (0.4–4.2MHz) O (0.4–4.2MHz) O (32.768 kHz) 0.95 µs (f OSC = 4.2 MHz) 2.7 to 6.0 100-pin plastic QFP (FP-100B) 100-pin plastic QFP (FP-100A) 100-pin plastic TQFP (TFP-100B) Guaranteed operation temperature (˚C) –20 to +75 2.7 to 5.5 — HD404829R 16,384 HD4074829 16,384PROM Minimum instruction execution time Operating voltage (V) Package 4 Pin Arrangement AVCC AN 0 AN 1 AN 2 AN 3 AV SS TEST OSC 1 OSC 2 RESET X1 X2 GND D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 /STOPC D11 /INT0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 FP-100B TFP-100B Top view R00 /INT1 R01 /INT2 R02 /INT3 R03 /INT4 R10 /TOB R11 /TOC R12 /TOD R13 /EVNB R20 /EVND R21 /SCK R22 /SI R23 /SO R30 /SEG1 R31 /SEG2 R32 /SEG3 R33 /SEG4 R40 /SEG5 R41 /SEG6 R42 /SEG7 R43 /SEG8 R50 /SEG9 R51 /SEG10 R52 /SEG11 R53 /SEG12 R60 /SEG13 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 75 74 73 72 71 70 69 68 67 66 65 64 63 62 61 60 59 58 57 56 55 54 53 52 51 100 99 98 97 96 95 94 93 92 91 90 89 88 87 86 85 84 83 82 81 80 79 78 77 76 NUMG NUMO NUMO VCC V3 V2 V1 COM4
